Seriously Shisha 120ml at a Glance

Seriously Shisha 120ml is a large-format bottled e-liquid from the Seriously range, built around a shisha-style flavour and sold as a shortfill. That means it arrives in a 120ml bottle, it is supplied at 0mg nicotine, and it is designed to be vaped in a refillable tank or a refillable pod device rather than thrown away after a few days like a single-use product. If you have only ever vaped disposables or pre-filled pods, a bottle like this is a different way of buying and using vape liquid, and it is worth understanding the basics before you order.

The headline facts a buyer usually wants in one place are these:

• Format: 120ml bottle, supplied as a shortfill with space left in the bottle for nicotine shots
• Typical fill: 100ml of 0mg liquid in the 120ml bottle, which leaves 20ml of headroom for two 10ml nicotine shots (always confirm the exact fill volume printed on the label you receive)
• Nicotine as supplied: 0mg/ml
• Flavour direction: shisha-inspired, in the sweet, layered style associated with hookah-lounge blends
• Best suited to: sub-ohm tanks, mesh-coil tanks and open refillable pod kits
• Age restriction: 18+ only, in line with UK law

The Seriously brand sits within the wider Doozy family and focuses on large, good-value bottles rather than the tiny 10ml format. The shisha flavour is aimed at adults who like a rounded, sweet, slightly cooling profile instead of a sharp menthol hit or a dessert-heavy custard. It is a flavour style that has grown steadily in UK vape shops, partly because many adult smokers who switched found that fruit-and-cool blends were easier to live with than tobacco imitations.

This page walks through everything a first-time or returning shortfill buyer tends to ask. We cover the shortfill format, how the flavour behaves, how much vaping you should expect from 100ml, which hardware suits it, how to add nicotine safely, how to use and look after the bottle, what to do when something goes wrong, and how the value stacks up against disposables and other shisha-style options. We have tried to keep it practical and honest, including the cases where this product is not the right fit.

What the 120ml Shortfill Format Actually Means

UK rules cap any e-liquid bottle that contains nicotine at 10ml, and cap nicotine strength at 20mg/ml. Those limits do not apply to liquid that has no nicotine in it, which is why a 120ml bottle of 0mg liquid can legally exist. The industry solution is the shortfill: the flavour base is sold in an oversized bottle at zero nicotine, and the bottle is filled to roughly 100ml so there is physical room to add nicotine afterwards.

The 20ml of empty space is the whole point of the 120ml size. Two 10ml nicotine shots fit into it, and the result is a full 120ml of liquid at a modest nicotine strength. A shot is simply a 10ml bottle of nicotine in a neutral base, usually in 18mg or 20mg strengths, which you buy separately. If you do not want nicotine at all, you leave the headroom empty and vape the 0mg liquid exactly as supplied.

Some practical points about the format that catch newcomers out:

• It is a refill, not a device. You need a refillable tank or pod to use it. It does not plug into anything on its own.
• The bottle is not the same as a 10ml. The large chubby bottle has a narrow nozzle designed to fit most tank fill ports, and it is meant to be squeezed gently, not shaken like a drinks bottle.
• Nicotine is optional. Many shortfill buyers vape at 3mg or 6mg once shots are added, but some vape it at 0mg because they have already stepped down.
• The ratio is on the label. The VG/PG split is printed on the bottle. Shortfills in this style are commonly high in VG, which suits sub-ohm and mesh setups, but you should check the label rather than assume.

Why do shortfills exist at all? Cost is one reason. Buying 100ml in one bottle works out cheaper per millilitre than buying ten separate 10ml bottles, because there is less packaging, less handling and less duty on the unit. The other reason is convenience: one bottle can last several weeks for a moderate vaper, which means fewer orders and less plastic through the door.

One caution before moving on. A 0mg shortfill is not nicotine-free once you add shots, and the strength you end up with depends on the shot you choose. A later section on nicotine strength shows the arithmetic so you know exactly what you are mixing.

Flavour Profile: How a Shisha-Style E-Liquid Is Built

Shisha flavours in vaping borrow their identity from the hookah lounge: sweet, rounded, a little floral or fruity, and often with a cooling edge that arrives on the exhale. They tend to be less jagged than a pure menthol and less heavy than a dessert flavour. The appeal is that they feel layered rather than flat, which matters when you are going to vape a lot of the same bottle over several weeks.

Seriously Shisha 120ml follows that general direction. Expect a sweet base note on the inhale, a fruit-led middle, and a lighter cool finish rather than a hard icy blast. We describe it as shisha-style deliberately: this is a vape flavour, not a hookah, and it contains no tobacco. If you want to check the exact notes the manufacturer lists, read the description on the product page and the label on the bottle, because blends are occasionally tweaked between batches.

A few things about flavour behaviour are worth knowing so that your first tank does not disappoint:

• Give it a short rest. New bottles often taste slightly sharper or flatter on day one. After a day or two of standing, or after adding a nicotine shot and shaking gently, the blend usually rounds out.
• Coil temperature changes everything. At lower wattage, sweet and cool notes come through clearly. Push the wattage high and the cooling can thin out while the sweetness gets sharper.
• Fresh cotton matters. A new coil gives the cleanest read of the flavour. A tired coil makes any shisha blend taste muddy, which is not the juice's fault.
• Nicotine adds throat feel. Adding shots will give the vape a little more bite. Zero-nicotine versions feel smoother and a touch sweeter.

Sweet, fruity-cool flavours also have a known quirk: palate fatigue, sometimes called vaper's tongue, where you stop tasting a flavour you have vaped for days. If that happens, change to a different flavour for a couple of days, drink some water, and come back. This is another reason many shortfill buyers keep two or three bottles in rotation instead of committing to one.

Finally, remember that taste is personal. A shisha profile that one person describes as smooth and sweet may feel too cooling or too sugary for another. If you are unsure, our related shisha and fruit-and-ice ranges let you compare similar styles before you commit to a large bottle.

Performance and Puff Delivery: What to Expect From 100ml

Because this is a bottle rather than a self-contained device, there is no puff count printed on the pack the way there is on a disposable. What you can estimate instead is how long the liquid will last, which is the honest measure of performance for a shortfill. The figures below are rough planning numbers, not guarantees, and real-world use varies a lot.

As a rule of thumb, a moderate vaper using a mesh-coil or low-power sub-ohm tank might get through 3 to 5ml per day. A heavy sub-ohm user pushing high wattage can use 8 to 10ml per day or more. A pod user on a low-wattage open pod kit may use 1 to 3ml per day. On those numbers, 100ml lasts roughly:

• Light use (1 to 3ml/day): around five to ten weeks
• Moderate use (3 to 5ml/day): around three to five weeks
• Heavy use (8 to 10ml/day): around ten to twelve days

Comparing with disposables helps put that in context. A typical single-use vape was sold on the basis of roughly 600 puffs from about 2ml of liquid, which is a little over 300 puffs per millilitre. By that crude yardstick, 100ml represents tens of thousands of puffs, though real tank puffs are longer and heavier than disposable puffs, so the comparison is only indicative.

Vapour production and throat hit depend almost entirely on your hardware and your settings rather than on the bottle itself. A high-VG liquid produces thicker vapour and a softer throat hit. Higher wattage produces more vapour and a warmer inhale. Higher nicotine strength increases throat hit regardless of the device.

On flavour consistency across a bottle, shortfills generally hold their character well as long as the cap is closed and the bottle is stored out of direct light and heat. If you notice the flavour dulling after a few weeks, look at your coil first, then your storage conditions, before blaming the liquid. In a later section on troubleshooting we cover the usual causes of weak flavour, gurgling and leaking.

Finally, a note on being realistic about airflow. Open airflow with a mesh coil gives bigger clouds but uses more liquid. Tighter airflow with a restricted lung inhale uses far less, and tends to suit people who switched from smoking and want a familiar feel.

Design and Build Quality: The Bottle, Cap and Label

With a bottled e-liquid, build quality is about the packaging rather than the electronics. It sounds minor, but the bottle design affects how easy it is to fill a tank cleanly, how safely you can store it, and how long the liquid stays in good condition.

The 120ml Seriously bottle is the familiar soft-plastic chubby unicorn style: a rounded body that you can squeeze, and a narrow tapered nozzle that sits inside the tank fill port. This design has a few real advantages:

• Squeeze control. A soft body lets you dispense small amounts gradually, which reduces spills when you are topping up a small pod.
• Tamper-evident, child-resistant cap. The cap should arrive sealed and require a push-and-turn action to open. This is a legal requirement for UK e-liquid packaging and exists to keep the product away from children.
• Narrow nozzle. A tapered tip fits most tank fill ports. If your device has an unusually small fill hole, check before buying, because a tiny port can still be awkward with a thick high-VG liquid.
• Headroom for shots. The unfilled space inside the bottle is intentional and gives you the room needed for nicotine shots and a gentle swirl.

The label carries the information you are required to see in the UK: the product name, the nicotine strength, the ingredient list, the VG/PG ratio, the batch and expiry information, and the health warnings. Take a moment to read it when the bottle arrives. If you intend to add nicotine, it also tells you the volume of liquid already in the bottle, which you need for your strength calculation.

As for weaknesses, soft plastic can be punctured by sharp objects, and a loose cap can leave residue around the thread. A few simple habits help: wipe the nozzle after filling, store the bottle upright, and keep it in the original box or a drawer. Do not leave it in a hot car or on a sunny windowsill, because heat and light degrade flavour and can accelerate colour change.

Disposal is a practical consideration too. Once the bottle is empty, rinse it and check your local council's guidance on household plastic recycling, as rules vary between areas. Never pour leftover liquid down a drain or into a bin without checking local advice.

Coil and Mesh Technology: Matching the Liquid to Your Tank

The liquid is only half of the equation. The coil inside your tank decides how that liquid is heated, and a mismatch between liquid and coil is the commonest reason a good bottle gets blamed for a poor vape. Seriously Shisha 120ml is a high-VG style liquid, so it generally behaves best in hardware that is designed for thicker e-liquid.

There are three broad hardware families worth thinking about:

• Sub-ohm tanks with mesh coils. Mesh coils use a flat mesh heating element rather than a round wire. Common resistances run from about 0.15 to 0.4 ohms, usually with a recommended wattage range printed on the coil. Mesh spreads heat evenly across more surface area, which tends to give a consistent flavour and quick ramp-up. It suits big bottles because it wicks thick liquid reliably.
• Sub-ohm tanks with round-wire coils. Traditional coils at 0.2 to 0.5 ohms still work well. They are often cheaper and a little more forgiving at lower power, although mesh generally has the edge on flavour consistency.
• Open refillable pod kits. Many pod devices use coils between 0.6 and 1.2 ohms. These run at lower wattages, around 10 to 25 watts, and they are a good bridge from disposables. High-VG liquid can be a little thick for the tightest pod coils, so check that your pod is rated for it. If the manufacturer recommends 50VG or higher, you are fine; if it only lists 50/50 or lower, expect slower wicking.

Setting up a new coil properly makes a visible difference to flavour. Prime the coil by dripping a few drops straight onto the cotton, fill the tank, then wait five to ten minutes so the cotton soaks fully. Start at the bottom of the recommended wattage range and work up gradually. Dry-hitting a coil that has not saturated burns the cotton, and burnt cotton is the main reason a fresh coil suddenly tastes harsh.

Coil life depends on how sweet the liquid is and how hard you push it. Sweet, sugary flavours tend to caramelise on the coil, so a shisha blend may need a replacement every one to three weeks for a moderate user. Signs it is time include muted flavour, a faint burnt taste, or gurgling that did not exist before. Used coils should go into household waste only if your local council allows it; otherwise use a drop-off point that accepts small electrical and metal waste.

Battery and Charging: Powering the Hardware You Pair It With

A bottle of e-liquid has no battery of its own, so the battery question here is about the device you vape it in. It is still one of the most important parts of the setup, because a battery that is too small or badly cared for makes any liquid feel disappointing.

Battery capacity is quoted in milliamp-hours (mAh), and the right size depends on your device type and usage:

• Small pod kits: typically 400 to 1,000mAh. Enough for a day of light use, and often recharged overnight.
• Mid-power mod pods and AIO devices: typically 1,000 to 2,000mAh. A comfortable one-day battery for most moderate vapers.
• Box mods with removable 18650 or 21700 cells: usually 2,500 to 5,000mAh per cell. These suit heavy users and sub-ohm tanks running at higher wattage.

Charging habits matter for both safety and longevity. Follow these basics:

• Use the cable supplied with the device, or a quality replacement from a reputable seller. Cheap unbranded chargers are a common cause of battery problems.
• Do not leave a device charging unattended overnight on a soft surface such as a bed or sofa.
• Keep removable cells in a case, never loose in a pocket with keys or coins.
• If a battery is swollen, hot, or damaged, stop using it. Take it to a recycling point rather than the bin.
• Avoid fully draining a lithium cell regularly. Topping up between 20% and 80% extends its working life.

Battery recycling is a legal and practical matter in the UK. Lithium batteries and vape devices must never go in household rubbish or normal recycling because they can cause fires in collection vehicles and waste sites. Use a household waste recycling centre, a supermarket battery bin, or a retailer take-back scheme. Since the single-use vape ban took effect in 2025, reusable refillable kits paired with bottles such as this one have become the mainstream route in the UK, and they produce much less electrical waste per month of vaping.

One more point worth making: your battery and your coil interact. A coil rated for 40 to 60 watts on a weak small battery will sag and perform poorly. If your flavour seems flat and your device is struggling, check that the wattage and battery capacity match before you change the liquid.

Choosing a Nicotine Strength for a 0mg Shortfill

Seriously Shisha 120ml is supplied at 0mg, and the strength you end up with is up to you. This section is for adults who currently use nicotine and want to add it, or who want to understand what they are doing before they do it. If you do not use nicotine, there is no need to add any, and we would not suggest starting.

The arithmetic is straightforward. In a bottle that already holds 100ml of 0mg liquid, you add shots and the final strength equals the total nicotine divided by the total volume. Some common examples, assuming a standard 10ml shot at 18mg/ml and a final volume of roughly 110 to 120ml:

• One 10ml shot (18mg): about 1.6mg/ml in roughly 110ml. A very light level, suitable for people already close to zero.
• Two 10ml shots (18mg): about 3mg/ml in 120ml. This is the most common arrangement for shortfills and the reason the bottle has 20ml of headroom.
• Two 10ml shots (20mg): about 3.3mg/ml in 120ml, a touch stronger.

Higher strengths such as 6mg need a different approach. With only 20ml of headroom in the bottle you cannot reach 6mg by shots alone without removing some liquid first, and we would suggest buying a 10ml nic salt or freebase bottle at the target strength instead of trying to engineer it.

Some guidance on picking a level:

• Former heavy smokers using sub-ohm tanks: often 3mg to 6mg, because a big vape delivers a lot of liquid per puff.
• Moderate former smokers using mid-power devices: often 3mg.
• Light users or those cutting down: 0mg to 1.5mg.
• Pod users on tight airflow: most pod users prefer nic salts at higher strengths in smaller bottles, so a 3mg freebase shortfill may feel too weak in a restricted device. That is a hardware-fit question rather than a problem with the liquid.

For context, the 20mg/ml ceiling in UK law applies to nicotine-containing e-liquids and disposables alike, and it is the reason shots top out at 20mg. After adding a shot, close the cap tightly, shake or swirl gently for a minute, and let it rest for several hours. Nicotine tends to settle into the liquid more evenly after some time.

If you are under 18, or if you do not currently use nicotine products, you should not use nicotine at all. Nicotine is addictive, and the shop will not sell it to under-18s.

Who Seriously Shisha 120ml Is For, and Who Should Skip It

Every product suits some vapers better than others. Here is an honest breakdown, so you do not have to find out the hard way.

It is likely a good fit if you:

• Already own a refillable tank or open pod and want to cut your running costs compared with disposables or pre-filled pods
• Enjoy sweet, fruity and lightly cool flavours and have found plain menthol too sharp
• Vape enough that a 100ml bottle will be finished within six to eight weeks, so it stays fresh
• Are comfortable adding a nicotine shot or want to vape at 0mg
• Like a flavour that works at lower wattage and still tastes good in a mesh coil
• Want a bottle that is useful in more than one device, from a small AIO to a larger sub-ohm tank

It is probably not the right choice if you:

• Have never used a refillable device. A bottle without hardware does nothing. If you are starting from scratch, buy a starter kit and a small bottle first, then upgrade to a large format once you know your preferences.
• Need a high-strength nic salt hit. Nic salts at 10 to 20mg are made for tight pod devices and for people who need a quick, strong effect. A 3mg shortfill will not give you that.
• Want a closed pod system. Some pod kits only accept proprietary pre-filled pods and will not work with bottled liquid.
• Prefer variety. A 100ml bottle commits you to one flavour for weeks. If you get bored easily, smaller bottles or a few different 50ml shortfills may suit you better.
• Are pregnant, or have a medical condition that nicotine could affect. Talk to a GP or stop-smoking service for guidance.

A few other buyer types come up regularly. Hobbyists who like to mix their own shots and tweak their strength are well served by shortfills. Adults who have switched from smoking and want something cheaper than disposables find the economics compelling. And people who have used shisha-flavoured disposables, such as the lounge-style flavours from other brands, often come to bottled liquid precisely because it allows them to keep the flavour while reducing waste. As always, vaping is for adults who already smoke or use nicotine, and it is not recommended for anyone who does not.

How to Use Seriously Shisha 120ml, Step by Step

Using a shortfill is simple once you have done it once. If it is your first large bottle, follow these steps in order and go slowly. Most mistakes come from rushing.

Step 1: Check the bottle. Make sure the tamper seal is intact and read the label. Note the fill volume, the VG/PG ratio and the batch information.

Step 2: Decide on nicotine. If you want to add shots, open the bottle, add them, and close the cap tightly. If you are vaping at 0mg, skip this step.

Step 3: Mix. Gently swirl or tilt the bottle for about a minute. A hard shake can introduce air bubbles that make the liquid foamy for a while. Let it stand for a few hours, ideally overnight, if you added nicotine.

Step 4: Prepare the tank. Switch the device off, unscrew the tank top or open the fill port, and keep the tank upright. Make sure the coil is fitted and the airflow is fully closed while you fill to avoid flooding.

Step 5: Fill carefully. Squeeze the bottle gently so the liquid runs down the side of the tank wall, not directly onto the coil chimney. Stop below the maximum fill line. Leave a small air gap, because overfilling is a common source of leaks.

Step 6: Let the coil soak. Wait five to ten minutes before your first puff. If the coil is new, prime it as described in the coil section.

Step 7: Start low, then adjust. Begin at the lower end of the coil's wattage range. Take a couple of gentle puffs, then increase until the flavour and warmth feel right.

Step 8: Keep it tidy. Wipe the nozzle after each refill, close the cap fully and store the bottle upright.

A few general habits make life easier:

• Keep liquid and devices away from children and pets at all times
• Do not mix different brands in the same tank, because it makes it hard to tell what is causing a problem
• Rinse the tank thoroughly when you change flavour
• Do not vape while sleeping or driving
• If you spill liquid on skin, wash it off straight away with soap and water

If you are switching from a single-use vape, give yourself a few days to adjust. Tank vaping feels different: the puffs are usually longer, the airflow is more open, and the vapour is warmer. Most people settle within a week.

Troubleshooting: Weak Flavour, Leaks, Gurgling and Burnt Taste

Almost every problem people blame on e-liquid turns out to be a hardware or technique issue. Work through these in order before you decide the bottle is at fault.

Weak or muted flavour. The usual causes are a tired coil, palate fatigue, or wattage set too high. Replace the coil if it is more than two weeks old, rinse the tank, and drop the wattage by a few watts. Try a different flavour for a day to reset your taste buds.

Burnt or harsh taste. This is nearly always a dry or partly dry coil. Possible reasons: the coil was not primed properly, the tank ran low, or airflow is too open for the liquid thickness. Replace the coil, let it soak longer, and avoid chain vaping at high power.

Gurgling or spitting. Often a sign of too much liquid reaching the coil. Reduce fill level, close the airflow slightly, and wipe condensation from the drip tip. A gentle blow back through the mouthpiece clears the airway on some tanks.

Leaking from the tank. Check the seals and the screw rings are tight, make sure the coil is seated properly, and do not overfill. Hot cars and changes in altitude can also push liquid out, so store tanks upright and empty them before flights.

Slow wicking or dry hits. High-VG liquid is thicker, and a tight pod coil may struggle with it. Increase the wattage slightly, open the airflow a bit, or switch to a coil designed for high-VG liquids.

Liquid looks darker or smells different. Natural colour change happens over time, especially with sweeteners, and it is not necessarily a sign of spoilage. If the smell is sour or chemical, stop using it and contact the shop.

Nicotine feels too strong or too weak. Adjust gradually. Too strong: use fewer shots next time or dilute with a 0mg bottle. Too weak: consider a slightly higher strength or a different device with tighter airflow.

The bottle leaks in transit. Soft bottles can seep if the cap is loose or if pressure changes during delivery. Check the cap on arrival, and if there is damage, get in touch with a photo so we can sort a replacement under our returns policy.

If none of these apply, take a note of your coil type, wattage, fill date and bottle batch number. That information helps us diagnose the issue quickly if you contact customer support.

Value for Money and How It Compares With the Alternatives

Value in vaping comes down to cost per millilitre, how long a bottle lasts, and what else you have to buy to use it. A 100ml shortfill almost always wins on the first measure, but you need hardware to use it. Here is the honest comparison.

Versus 10ml nic salts. Ten 10ml bottles of nic salts cost considerably more than a single 100ml bottle at 0mg plus a couple of shots. Nic salts have a role, though: they deliver a smoother high-strength hit in small pod devices, which a 3mg shortfill cannot match. If you vape on a pod kit at 20mg, salts will usually suit you better. If you vape in a tank at lower strength, a shortfill is clearly cheaper over a month. Examples from the shisha category include the Bar Juice 5000 nic salt range, which is a 10ml format at salt strengths.

Versus shisha-style pre-filled devices. Products like the Hayati Pro Max range and Elf Bar shisha editions are convenient: you open the pack and use it. The cost is higher per millilitre, and there is more electrical waste. The advantage is zero setup. If you want zero effort, they are fine. If you want to spend less over a year, a refillable setup with a big bottle gets you there.

Versus other shortfills. The 100ml shortfill market is crowded. Many brands sell flavours in a similar sweet, fruity and cool style, and plenty of them are decent. Seriously competes mainly on bottle size, price and flavour variety rather than on any technical edge. If you already have a favourite shortfill brand, switching because of this page alone is not necessary. If you are new to shortfills, this is a reasonable place to start.

To put numbers on the running cost: if you use 4ml a day, a 100ml bottle lasts around 25 days. Spread over that time, the liquid cost per day is a fraction of what the equivalent number of disposables would cost. Add a coil every two weeks and the occasional nicotine shot, and the total remains well under a regular disposable habit.

Hidden costs to keep in mind include the initial hardware outlay, replacement coils, and the nicotine shots if you use them. If you vape only occasionally, a big bottle may go stale before you finish it, so buy a size that matches your use.

Overall, Seriously Shisha 120ml makes sense for people who vape regularly, have refillable hardware, and want to lower their monthly spend. It does not make sense as a first-ever vape purchase without equipment.
