Seriously Fusionz Shortfill E-Liquid By Doozy: what you are buying

Seriously Fusionz Shortfill E-Liquid By Doozy is part of the Seriously Fusionz Shortfill E-Liquid By Doozy range, priced at £7.99. We list what the product actually is rather than padding it with specifications we cannot verify.

The full Doozy range is at Doozy, and this line alone runs to 7 flavours. Everything we ship is genuine UK-compliant stock.

Getting the best from the bottle

UK rules cap nicotine e-liquid at 10ml per bottle, so restocking is part of the routine.

  • Prime a fresh coil or pod before the first draw: fill it, then wait a few minutes so the wick soaks properly.
  • Store bottles upright, out of sunlight and away from heat, which keeps the flavour truer for longer.
  • A burnt taste usually means the wick has dried out rather than the liquid being at fault.
  • Keep bottles away from children and pets, and use the child-resistant cap as intended.

None of that is complicated, but it is the difference between a pod that tastes right to the end and one that does not.

Choosing your nicotine strength

This e-liquid is listed in 0mg. The 20mg ceiling is a legal limit under UK rules, not a brand decision.

  • 0mg contains no nicotine and is chosen for the flavour and the ritual alone.

Going too low often means vaping more to compensate, which defeats the point. 10mg options and 20mg options are browsable separately if you want to compare.

Ordering, delivery and the legal bit

This is an 18+ product and age verification applies to every order. Nicotine is addictive, and these products are for adults who already smoke or vape.

Browse all e-liquids, or head to the sale if price is the deciding factor. Questions about compatibility are worth asking before you order rather than after.

Other flavours in the Seriously Fusionz Shortfill E-Liquid By Doozy range

Sticking with the line you already like is easier than starting from scratch elsewhere. 7 flavours sit under this name, including:

Rotating between two profiles keeps both tasting sharper for longer.

What the multibuy actually saves you

The offer on this line is buy 2 for £14. At £7.99 each, 2 would normally be £15.98, so the bundle saves £1.98 and works out at £7.00 apiece.

That sits under the £20.00 free delivery threshold, so either add something small or take the offer twice. You can mix flavours within the offer, so use it to try something new alongside a known favourite.

Baskets above £20 ship free within the UK. Same-day dispatch applies on weekday orders in before 4pm.

A note on puff ratings and value

Puff ratings sell products, but they are laboratory figures. Where no rating is published, we would rather say so than invent one. A heavy user and a light user get very different results from the same product.

After a fortnight you will know your own consumption, which beats any number on the box.

Where this sits against the rest of our range

Context matters more than any single listing. Bottled e-liquid works out cheaper per millilitre and lets you pick your own strength, while prefilled pods trade some of that value for convenience and no mess.

The split usually comes down to whether you mind carrying a bottle. Vape kits are the other half of the equation if you are still deciding on hardware.

Where this sits in the Doozy range

Brands are easier to judge by their range than by any one item in it. We stock 106 Doozy products, running from £2.69 to £9.99. That breadth means you can usually stay inside the brand when you want a change, rather than starting over somewhere else.

The full lineup is on the Doozy page. Other Doozy products worth a look:

Staying within a brand you already rate is the low risk way to try something new.

How it compares to the rest of the category

The useful question is not what it costs, but what else that money buys. We list 736 products in this category. At £7.99, this one sits in the middle of the market.

  • Multibuy deals are where the price per unit drops hardest, and they can be mixed across flavours.
  • Reduced lines carry 1,558 products if the budget is the deciding factor.
  • Prefilled pods cost more per millilitre but remove the refilling entirely.

Which way you go usually comes down to whether convenience or cost matters more on the day.

The running cost, worked out

Headline prices hide the number that actually matters, which is what a week costs you.

We would rather leave the arithmetic blank than guess at a rating.

  • The buy 2 for £14 offer is the single biggest lever on that number.
  • Baskets over £20.00 ship free in the UK, so building to that threshold beats paying postage twice.
  • Nicotine strength changes consumption: many adults find a higher strength means reaching for the device less often.

Seriously Fusionz Shortfill E-Liquid By Doozy against the rest of the line

The quickest way to judge a flavour is against its own siblings, not against the whole shop. There are 7 options under this name:

Palate fatigue is real: rotating two profiles keeps both tasting sharper for longer. The buy 2 for £14 offer makes that cheap to do.

Why the UK market looks like this

Some of what you see on the shelf is regulation rather than brand choice. UK rules cap nicotine at 20mg per ml, nicotine e-liquid bottles at 10ml, and prefilled pods and tanks at 2ml. Those three numbers explain most of the format quirks in this category.

The end of single-use disposables changed what sits on the shelf. Rechargeable kits with replaceable pods took their place, which is why a device now comes with a charging port and a pod you swap rather than a sealed unit you bin. For most people it works out cheaper over a month, provided you stay on one platform.

Everything we sell is UK-compliant stock bought through UK distribution. This is an 18+ product and orders are verified before dispatch.

More flavours in this line

The rest of the line, if you want to compare before choosing.

Rotating a pair is the simplest fix for flavour fatigue.

Buying this as a first purchase

New to this format? Three decisions cover almost everything.

  1. Format. A bottle is the cheapest way to vape per millilitre, but you refill it yourself. Prefilled pods remove that job at a higher cost.
  2. Strength. This comes in 0mg. Heavier former smokers usually start high and step down.
  3. Flavour. Pick two from different families rather than committing to one.

Get those three right and the rest is detail. The deals page is the cheapest way to try more than one at a time.

Looking after it, and what goes wrong

The faults people blame on a product are usually storage or priming.

  • Prime before the first draw. Fill, then wait a few minutes so the wick soaks fully. A dry first pull is what burns a coil.
  • Keep it cool and upright. Heat thins liquid and pushes it through seals, which is why a hot car is the usual cause of a leak.
  • Muted flavour is often you, not it. Palate fatigue is common on a single flavour, and rotating to a second profile resets it.
  • Store away from children and pets, and recycle spent hardware rather than binning it loose.

These are small habits that pay back in flavour consistency.

Delivery, returns and buying with confidence

Ordering is deliberately simple. Weekday orders placed before 4pm are dispatched the same day, and UK delivery is free once your basket reaches £20.00. Delivery choices, including tracked services, appear at checkout.

We cannot resell an opened consumable, so opened items are outside the returns policy. Anything faulty or wrongly sent is our problem to fix, not yours. This is an 18+ purchase and orders are age-checked before they ship.

Nicotine is an addictive substance and these products are intended for adults who already smoke or vape.

What changed when disposables were banned

The shelf you are shopping from looks nothing like it did two years ago. Single-use disposable vapes were banned in the UK, and the market replaced them with rechargeable devices that take replaceable pods. The experience is deliberately similar: prefilled, no measuring, no mess. The difference is that the battery survives the flavour, so you replace a pod for a couple of pounds rather than the whole unit.

For most people the change was an improvement, financially and otherwise. A device bought once and fed with pods costs less over a month than a stream of sealed units, and produces far less waste. It also changed how you shop: the decision splits into hardware first, then consumables, rather than being one purchase repeated endlessly.

Everything we list meets the current rules. That means 2ml pods, 10ml nicotine bottles and a 20mg strength ceiling, with age verification on every order. Rechargeable kits and replacement pods are the two halves of that system if you are still assembling yours.

Building a rotation instead of buying one thing

Experienced vapers rarely buy one flavour in bulk, and new ones almost always do. Palate fatigue sets in faster than people expect. A profile you loved on day one can taste flat by day ten, not because the product changed but because your palate stopped noticing it.

The solution is simply how you buy. Keep two profiles from genuinely different families on the go, and alternate between them. Something sweet paired with something sharp, or a fruit paired with a menthol, resets the palate each time you switch. Two flavours in rotation will each last noticeably longer than either would alone.

Within this line alone there are options to pair with:

The buy 2 for £14 offer exists precisely for this, and it can be mixed across flavours rather than spent on one.

Pros & cons

Pros

  • Best value per ml in the category
  • Choose your own device and coil
  • Available in a wide strength ladder

Cons

  • Refilling can leak if you overfill
  • Coil priming has a small learning curve
  • You handle the bottle — less discreet than pods

Customer Buying Tips

  • Match the strength to how much you smoked: 20+/day → 10-20 mg nic salt; 10/day → 10 mg; under 5/day → 3-6 mg freebase.
  • Match the ratio to your device: pod kits take 50/50, sub-ohm tanks take 70/30 shortfill.
  • Don't overfill: leaving the airhole clear prevents gurgling and leaking.
  • Shake before use so the nicotine and flavour integrate evenly.

Frequently asked questions

Is there a multibuy on this?

Yes, the offer is buy 2 for £14, and it can be mixed across qualifying flavours rather than being limited to this one.

Why is the puff rating so high when a pod only holds 2ml?

Because UK rules cap a prefilled pod at 2ml, a five-figure rating describes what the system delivers across the pods you use, not what sits in one pod.

Can I mix flavours in one order?

Yes. Multibuy offers apply across the qualifying range, so you can spread a bundle over several flavours instead of committing to one.

What if I do not like the flavour?

Flavour is personal and we cannot resell an opened consumable, so the multibuys are the low risk way to try more than one. Buying a pair from different families is the usual approach.

How many puffs does the Seriously Fusionz Shortfill E-Liquid By Doozy give?

No puff rating is published for this listing, so we do not quote one. How long it lasts depends on your device and how often you vape.

What nicotine strengths does it come in?

It is listed in 0mg. UK law caps nicotine at 20mg per ml, so that is the strongest available from any retailer.

What does this flavour actually taste like?

The listing name is the best guide we can give without inventing tasting notes. If you want a safer bet, pick a family you already enjoy.
