Uwell Viscore 8000 Blueberry Sour Raspberry Kit Overview

The Uwell Viscore 8000 Puffs Pod Kit in Blueberry Sour Raspberry is a prefilled nicotine salt pod device, priced at £9.49 and available in 10mg or 20mg. It arrives ready to use. There is no bottle to open, no tank to fill and no coil to prime, which is exactly why this format has become a familiar choice for adults who want a low-fuss alternative to smoking.

The brand behind it is Uwell, a manufacturer that built its reputation on refillable pod systems before moving into sealed, prefilled hardware. The Viscore line applies that engineering background to a simpler product: a slim body, a pod that seats into it, and a flavour already inside. If you have been browsing our wider range of vape kits, this one sits at the easy end, aimed at people who would rather swap a pod than learn a menu.

The listing name carries two numbers that need explaining, and we cover both properly further down. The first is 8,000, the manufacturer's puff rating for the device. The second is "40K Puffs", a label that comes from the way the product was named upstream. Neither number is a promise about how long your kit will last, and we would rather say so now than have you discover it on day three.

The flavour is the main draw. Blueberry Sour Raspberry pairs two berry notes with a tart, slightly sharp finish, so it is aimed at fruit fans who find straight sweet blends a little cloying. Because this is a prefilled kit, the flavour is fixed. What you taste on the first draw is what you taste on the last, which makes the choice at checkout more important than it would be with a refillable device.

Here is what you can rely on when you order this kit:

• A complete prefilled pod device, with no separate liquid needed
• Nicotine salt in your choice of 10mg or 20mg per millilitre
• A rated life of 8,000 puffs, which is an estimate and not a guarantee
• A price of £9.49 per kit at the time of writing
• Strictly 18 and over, with age checks at the point of sale

Everything else on this page is context, written to help you decide whether the kit fits your routine before you spend anything.

How the Prefilled Pod Format Actually Works

Think of this kit as two parts that click together. The body holds the battery and the electronics. The pod holds the liquid, the heating element and the mouthpiece in one sealed unit. When you draw on the mouthpiece, or press a button if your unit has one, the battery warms the element, the nicotine salt liquid in the wick turns to vapour, and the airflow carries it to your mouth. That is the entire mechanism, and the lack of anything to adjust is the point of the design.

Trade people call this a closed pod system. Closed simply means you do not open the pod to add liquid. When the liquid runs out, or the flavour fades, you remove the pod and fit a fresh one. That makes everyday use very predictable. There is no filling spill, no coil to pick, and no chance of pairing a coil with a liquid it was never designed to handle.

The nicotine format matters here too. Nicotine salt is noticeably smoother at a given strength than the freebase nicotine used in older tank setups, which is why a compact kit can offer 10mg and 20mg without feeling harsh in the throat. Salts also suit the modest power output that a small prefilled device runs at. In practice you can expect a fairly tight, gentle draw, nearer to the resistance of a cigarette than to the loose, airy pull of a large refillable tank.

What the format does not give you is adjustment. Kits like this rarely offer wattage dials or airflow rings to tune, and you should not expect a settings menu. If the pod is seated properly and the battery has charge, it works. If it does not, the troubleshooting section further down lists the likely causes in order, starting with the most common and the easiest to fix.

One habit is worth building from day one. Always push the pod fully home before the first draw, and push it again if the kit seems unresponsive. A pod sitting a millimetre proud is the single most common reason a brand new kit looks dead, and checking it takes two seconds. You should feel or hear it settle into place.

Blueberry Sour Raspberry Flavour Profile in Detail

Start with the blueberry, because it carries the base of the flavour. Expect a rounded, slightly jammy sweetness rather than a sharp, juicy burst, the kind of dark berry note you get from a baked blueberry muffin more than from a punnet of fresh fruit. It is the part of the profile that sits in the background and keeps the whole thing from tasting thin.

The raspberry sits on top. It is brighter and lighter, with a tart edge that lifts the blueberry and stops it turning heavy. Raspberry is one of the more recognisable notes in vape flavours, so most people pick it out on the first or second draw.

Then comes the sour element, which gives this flavour its character. It shows up as a sharp, slightly tingling lift on the inhale, usually felt at the sides of the tongue, and it fades quickly on the exhale to leave a sweet berry finish. If you have ever eaten sour berry sweets, you will know the pattern: a snap of acidity followed by sugar. It is meant to be refreshing rather than harsh, but taste is personal and some adults find sour blends a touch sharp.

A few things are worth bearing in mind about how this flavour behaves in practice:

• No cooling effect. The name does not mention ice or menthol, so do not expect a chilled sensation. If you want one, the Banana Ice version of the same kit is the obvious alternative.
• Fresh pods taste strongest. The first few hundred puffs usually show the flavour at its clearest, and some people notice a gentle softening towards the end of a pod's life.
• Longer, gentler draws help. Slow pulls let the sweetness come through. Short, hard pulls emphasise the sour edge.
• The flavour is fixed. The pod is sealed, so what you taste on day one is what you taste on the last day.

A caution on descriptions. These notes are our reading of the flavour name and of the way this style of blend normally behaves. The manufacturer does not publish a tasting sheet that we can quote, so treat this as a guide to what to expect and not as a guarantee of how it will taste to you.

Reading the 8,000 and 40K Puff Labels Honestly

Puff ratings are among the most misunderstood numbers in vaping, and this listing carries two of them, so it is worth slowing down.

The first is 8,000, the rating for the Viscore device. A puff rating is an estimate calculated by the manufacturer from how much liquid is in the pod and a test routine with a fixed draw length, a fixed gap between draws and a fixed power level. Change any of those and the figure moves. Real people do not vape like a test machine, so the number describes how a lab method scored the product and says very little about how long your own pod will last.

The second is 40K Puffs, which appears in the product name. This is a label carried over from the way the item was named by its supplier. We have kept it in the title so that anyone searching for it can find the page, but the device itself is rated at 8,000, and we would not plan around the larger figure. UK rules limit a prefilled pod to 2ml of liquid, and no single pod of that size can sensibly deliver 40,000 draws. The same ceiling applies to every kit in our big puff vape kits range, however large the number printed on the front.

A more useful way to think about it is cost per day. Take an illustrative figure of 150 puffs a day. If you reached the full 8,000, the kit would last about 53 days and cost roughly 18p a day at £9.49. If you reached half, 4,000 puffs, it would last about 27 days at roughly 36p a day. Both are reasonable for a pod kit, and neither figure is a promise.

If you simply want the biggest rating on the shelf, our 10000 puff vapes collection is where those listings live. Read those numbers with the same 2ml ceiling in mind, though. A larger figure on the box rarely means a proportionally longer life, and the honest comparison is always the price you pay against the days you actually get.

Specifications and Numbers at a Glance

Here are the figures we can stand behind, gathered in one place so you do not have to hunt through the page.

• Product: Uwell Viscore 8000 Puffs Pod Kit, Blueberry Sour Raspberry
• Format: prefilled closed pod kit with nicotine salt liquid
• Brand: Uwell
• Price: £9.49 per kit at the time of writing
• Nicotine strengths: 10mg and 20mg per millilitre
• Rated puffs: 8,000, a manufacturer estimate
• Pod liquid limit: 2ml, the maximum that UK rules allow for a pod
• Listing type: big puff vape kit

Some numbers are missing on purpose. We do not quote battery capacity, charging time, coil resistance or the exact volume of liquid in the pod, because those details are not in the information we hold for this listing, and a figure we cannot verify is worse than no figure at all. The packaging and the leaflet in the box are the sources to trust for those specifics.

Two derived numbers help put the specification in context. At £9.49 and 8,000 rated puffs, the price works out at about 0.12p per rated puff, which is a theoretical best case. And because nicotine strength is measured per millilitre, a full 2ml pod at 20mg per ml holds up to 40mg of nicotine in total, while a 10mg pod holds up to 20mg. Those totals are ceilings and not what you absorb, because the amount you take in depends on how you draw.

In short, the specification describes a deliberately simple device. The decisions left to you are strength and flavour, and the flavour question is settled by this page. That leaves nicotine strength as the one real choice at checkout, which the guide further down is written to help with.

Who the Uwell Viscore Suits and Who Should Skip It

Not every vaper wants a big, adjustable device, and this kit is firmly aimed at people who do not.

It tends to suit adults who currently smoke and want to try something simpler. The learning curve is short, the draw is gentle, and the lack of tweakable settings means there is nothing to get wrong. It also suits fruit fans who like a tart edge in their flavours, since the sour raspberry note is the main selling point and a plain sweet berry would not scratch the same itch.

Other people it often fits:

• Commuters and travellers who want a slim device that fits a jacket pocket
• Anyone who already owns a bulkier setup and wants a low maintenance backup
• People who dislike filling, spilling and coil swaps
• Buyers working to a small budget, since £9.49 is a modest outlay

It is less well matched to a few groups. If you enjoy fine tuning airflow and power, a sealed pod will feel limiting. If you like mixing your own liquid or trying a new bottle every week, a prefilled kit locks you into one flavour at a time, and refillable vape pods would serve you better. If you want large clouds, a compact kit will not deliver them, and that is by design.

One point has to be stated plainly. Vaping products contain nicotine, which is addictive. This kit is for adults aged 18 and over who already use nicotine. It is not for anyone under 18, for people who have never smoked or vaped, or for anyone who is pregnant or breastfeeding. If you are unsure whether it is right for you, speak to a pharmacist or your GP before buying.

A sensible way to decide is to ask what you want the device to do. If the answer is "work without fuss, taste of sour berries and cost under a tenner", this kit is built for that brief. If the answer involves tuning, mixing or heavy cloud production, look elsewhere in the range.

Choosing Between 10mg and 20mg Nicotine

Ten milligrams or twenty? This is the decision that matters most after flavour, and it is easier than it looks.

The figure on the pod is the amount of nicotine per millilitre of liquid. The UK ceiling for vaping liquid is 20mg per millilitre, so the 20mg option here is the strongest you can legally buy, and there is nothing stronger to graduate to. Both strengths in this kit are nicotine salt, the kind designed to feel smooth at higher concentrations. You can read more about the format in our nicotine salt e-liquids range, which uses the same chemistry in bottles.

As a rough guide, many adults choose by comparing with their current habit:

• 20mg is the usual starting point for people who smoke regularly, especially those at or above ten cigarettes a day, because the nicotine arrives quickly and tends to feel more satisfying with fewer draws.
• 10mg suits lighter or occasional smokers, social users, and people who find stronger salts too sharp in the throat.

There is a trade off to understand. A stronger pod usually means fewer puffs to feel satisfied, which can make the rated puff count stretch further in practice, while a lighter pod invites more frequent, more casual vaping. Neither is better in itself. The aim is a strength that feels comfortable without making you light-headed or unwell. If you feel dizzy, queasy or jittery, stop, put the device down and consider a lower strength next time.

A few practical points. Do not pick 20mg just because it is the maximum; if you are unsure, many people find 10mg the gentler place to begin, and moving up later is easy. Keep track of how much you are using, because it is easy to take in more nicotine than you intended when a flavour is pleasant and the device never needs refilling. Nicotine is addictive at any strength, and the information here is general guidance for adult users and not medical advice.

Getting Started Straight Out of the Box

Unboxing takes under a minute, but a few checks are worth doing before the first draw.

• Check the pack. The seals should be intact, the pod should look undamaged, and the box should carry the nicotine health warning and ingredient information that UK rules require. If anything looks wrong, do not use it and contact us.
• Remove all protective film. Peel off any sticker, plug or cap from the mouthpiece and the airflow openings. A single scrap of leftover plastic is enough to block the draw.
• Seat the pod. If the pod is separate from the body, press it firmly into the top until it settles. If it is already fitted, give it a gentle push to be sure.
• Check the charge. Some kits arrive with enough battery to start and some benefit from a short charge first. The leaflet will say which applies.
• Take two gentle draws. A new pod needs a moment for the wick to saturate. Use light, unhurried pulls rather than a hard drag, which can cause a dry or burnt taste.
• Settle into a rhythm. Pulls of a couple of seconds with a pause between them work well. There is no need to chain puff.

Activation varies in this category. Most kits in this class fire when you inhale, while some use a button. The leaflet in your box tells you which yours uses, and we would rather you follow it than rely on a general rule.

Before any of this, remember that purchases are age checked. Our age verification page explains what we ask for and why, and the rule is simple: you must be 18 or over to buy or to use the kit.

Finally, keep the packaging and the leaflet until the first pod is finished. They hold the warnings, the product information and the recycling guidance, and they are useful if you need to contact us about anything.

Battery, Charging and Sensible Storage

The battery decides how many hours you get between charges, and it is the part of a pod kit that people think about least until it gives out mid-afternoon.

The body of the kit holds a built in battery, and pod kits in this category are normally recharged through a USB cable. The box and leaflet tell you which type of port and which cable to use. We do not quote a capacity or a charging time, since neither appears in the information we hold, but one general principle holds: a small battery is fine for casual use and can need topping up daily if you vape heavily.

Sensible charging habits are simple.

• Use the cable supplied, or a good quality replacement, with a plain USB power source such as a laptop port or a low power wall adapter.
• Stay nearby while it charges, and avoid leaving it on overnight on a bed or sofa.
• Stop charging and contact us if the device becomes noticeably hot, swells or smells odd.
• Never use a cable with exposed wires or a bent connector.

Storage matters just as much. Keep the kit upright or flat at room temperature, away from radiators, windowsills and parked cars, where heat can thin the liquid and cause leaks. In cold weather the opposite happens: liquid thickens, and the first couple of draws can feel weak until the device warms in your hand. Do not carry it loose in a pocket or bag with keys or coins, which can short a battery.

Spare pods, if you buy them, should stay in their original packaging until needed. Keep everything out of reach of children and pets, because both the liquid and the device are hazardous if swallowed. If you travel, check your airline's current rules, as they vary on carrying vaping devices and spare batteries.

Honest Pros and Cons of This Kit

Every product has a trade off, and it helps to see them laid out without sales language.

The advantages:

• Simplicity. Nothing to fill, nothing to adjust, and nothing to prime beyond a couple of gentle draws.
• Low entry price. At £9.49 it is inexpensive to try.
• Nicotine salt in two strengths. A smooth draw at either 10mg or 20mg.
• Pocketable size. It travels easily and suits discreet use.
• A distinctive flavour. Blueberry Sour Raspberry has more character than a plain berry.
• Established hardware brand. Uwell has a track record in pod systems.

The limitations:

• Fixed flavour. You are committed to one profile per pod.
• Sour notes are subjective. Some people find tart blends sharper than expected.
• The puff rating is optimistic. Plan on getting less than 8,000, and treat 40K as a naming label.
• No adjustment. There are no airflow or power options to play with.
• Not refillable. When the pod is finished it needs replacing, which adds to the running cost and the waste.
• Nicotine dependence. Like every nicotine product, it is addictive.

Weighing these up, the kit makes most sense for adults who value ease over control. If price is the sticking point, check our vape deals for current multibuys and offers across the range. Deals change regularly, so we do not promise one on this particular flavour, but it costs nothing to look before you order. A second flavour bought at the same time can also be a practical way to avoid palate fatigue, which is the most common complaint about vaping a single fixed flavour all day.

Troubleshooting Common Problems and Basic Care

Most faults on a prefilled kit trace back to the same handful of causes, so work through them in order before assuming the device is faulty.

• Nothing happens when you draw. Check the pod is pushed fully home, the protective film is gone, and the battery has charge. Try a short charge, then test again.
• Weak vapour or thin flavour. A pod nearing the end of its life, or a lightly charged battery, are the usual causes. Cold weather plays a part too, so warm the device in your hand for a minute.
• Burnt or dry taste. This usually means the wick is running low on liquid. Stop, because pushing on makes the taste worse, and fit a new pod. Chain puffing also dries a wick faster than slow pacing does.
• Gurgling or spitting. Condensation in the airway can cause this. Point the mouthpiece downwards, wipe it with a dry tissue, and take a gentle draw.
• Leaking. Check that the pod is seated and undamaged, and wipe the contacts dry with a cloth. If liquid keeps escaping, stop using that pod.
• The flavour seems to fade. Over a long session your palate adjusts. Take a break, drink some water, and try again before deciding the pod is finished.

Never open, pierce or modify the pod or the battery, and do not try to refill a sealed pod. Wipe the outside with a dry cloth rather than water or cleaning sprays, and keep the contacts clean and free of residue.

If you have worked through the list and the kit still misbehaves, get in touch through our contact us page. Tell us your order number, the flavour and strength, and what happens when you draw. A short description and, if possible, a photo of the problem helps us sort things out quickly. Please do not carry on using a device that is hot, damaged or leaking, and keep it away from anything flammable until it has been looked at.

Alternatives, Pairing Ideas and Delivery Details

Before you check out, it is worth a quick look at where this kit sits against the alternatives and how the order itself works.

Within the same line, other flavours of the Viscore 8000 kit include Banana Ice and Blue Razz Lemonade, which give a very different mood from a sour berry. If you like the idea of a prefilled device but want to compare brands, formats and prices, our wider pod kits collection is a good next stop.

There is not much to pair with a kit like this, and that is part of its appeal. The one sensible extra is a second flavour. Many adults keep two on the go, perhaps a fruity one for the daytime and a cooler or sweeter one for the evening, simply to keep the experience fresh. Because each kit is self contained, switching is as easy as picking up the other device.

On the practical side, here is what to expect from us:

• Free UK delivery on orders over £20
• Orders placed before 4pm dispatch the same working day
• Every product is 100% genuine
• Age verification at the point of sale, because the products are strictly 18 and over

Our shipping information page has the current delivery options, timings and costs, along with guidance on what to do if a parcel arrives damaged or something is wrong with the order. Because vaping products are consumable and age restricted, we would ask you to check the page before ordering instead of assuming the rules match another retailer's.

Whatever you choose, open the parcel promptly, check the contents against your order, and keep the leaflet. If you spot a problem, contact us quickly with your order number and a clear description, and we will help you sort it out.
