Seriously Fusionz Shortfill E-Liquid By Doozy

Seriously Fusionz Shortfill E-Liquid by Doozy

Doozy built Seriously Fusionz around a simple idea: pair two fruits per bottle rather than one, so every inhale has a lead flavour and a chaser instead of a single flat note. It's a shortfill, meaning the bottle is only part-filled to leave room for nicotine shots, so you control the strength rather than being locked into whatever the bottle came with. That flexibility is the main reason UK vapers reach for shortfills over pre-mixed nic salt bottles in the first place.

The flavour range

The Seriously Fusionz line runs to around six blends, each built on the same fruit-pairing logic but aimed at a different mood. A few worth calling out by name:

• Cherry Sour Raspberry, a tart raspberry base with a rounder cherry finish. Less sweet than most cherry vapes, more of a sour-sweet see-saw.
• Fantasia Grape, a grape-forward mix without the artificial "grape soda" sharpness some e-liquids lean on. Softer and more drinkable across a full day.
• Strawberry Watermelon Ice, classic strawberry watermelon with a cooling finish. The ice is there to clean up the exhale rather than dominate it.
• Triple Berry Ice, a layered berry mix (think blackberry, blueberry, raspberry territory) with the same light menthol edge.

The rest of the range sticks to that same template, fruit pairing plus, in most cases, a cooled variant for anyone who prefers a chilled exhale over a warm one. If you're not sure where to start, the iced flavours are the safer bet for all-day vaping since the menthol keeps your palate from fatiguing, while Cherry Sour Raspberry and Fantasia Grape suit anyone who wants pure fruit with no cooling at all.

Setting it up without ruining the taste

Shortfills are almost always vaped through a sub-ohm tank or a refillable pod on a higher-wattage device, not a basic starter pen, so the flavour has enough vapour behind it to actually come through. A few habits make the difference between a clean vape and a muted or burnt one:

• Prime new coils before firing. Drip a couple of drops of e-liquid directly onto the coil's visible wicking holes and let the tank sit filled for five to ten minutes before the first puff. Fire a dry or under-primed coil and you'll get a burnt hit that no amount of top-ups will fix, that coil's flavour is gone for good.
• Keep the tank topped up. Running low and taking long pulls on a half-empty tank is one of the fastest ways to scorch a coil and dull the fruit notes into something flat and ashy.
• Match wattage to the coil's rating. Vaping under the recommended range mutes the flavour and can leave the liquid tasting thin; vaping well above it burns the wick faster and turns sweetness into a harsh, dry hit.
• Give it a shake before your first fill. Shortfills sit for a while between bottling and your basket, and the flavouring can settle slightly. A quick shake evens it back out.

Coils are consumable, expect flavour to fade gradually as one wears in, and swap it out once notes start turning muddy or the vape feels harsher than it did on day one.

Who this suits

Seriously Fusionz is aimed at vapers running sub-ohm tanks or high-airflow pod systems who want restaurant-menu style fruit combinations rather than a single-note strawberry or mango. It's a good fit if you've found single-flavour e-liquids get boring by the second bottle, or if you like switching between a fruity and an iced option depending on the day. It's less suited to anyone wanting a strong, immediate nicotine hit in a small device, for that, a nic salt bottle in a compact pod kit will feel more direct, since shortfills are built around bigger clouds and longer sessions rather than a fast throat hit.

How it compares to other shortfills

Against single-flavour shortfills, Seriously Fusionz's main draw is the pairing itself, you're getting a more complex profile without needing to mix two bottles yourself. Compared with heavily iced ranges that push menthol hard across the board, Doozy keeps the cooling optional and secondary, so flavours like Cherry Sour Raspberry and Fantasia Grape stay fruit-first. If you're coming from a nic salt pod system, the step up is mainly about format: bigger bottle, more vapour, and a strength you build yourself with nic shots rather than a fixed one out of the box.

Nicotine strength guidance

Shortfills are typically supplied with no nicotine, or a low level, and are designed to have one or more nicotine shots added afterwards to bring the whole bottle up to your preferred strength. Under UK TPD rules, nicotine-containing e-liquid is capped at 20mg/ml (2%), and that ceiling applies once your shots are mixed in, not just to the shot itself. A rough guide for choosing a shot strength:

• 0mg, no nicotine at all. Suitable for vapers who've already quit nicotine but still want the flavour and ritual, or for flavour-testing before committing a whole bottle to a strength.
• Lower strength (nearer 3mg once mixed), for established vapers on sub-ohm setups taking long, frequent pulls, where more vapour per puff means less nicotine is needed to feel satisfied.
• Higher strength (up to the 20mg/ml UK cap), better suited to smaller-volume devices or vapers who want a stronger hit per puff, though most sub-ohm shortfill users sit well below the cap since the format already delivers plenty of vapour.

These products are for adult smokers and vapers aged 18 and over only. If you're new to vaping or unsure which strength to start with, it's worth starting lower, you can always add another nic shot later, but you can't take nicotine back out once it's mixed in.

Care and storage

Keep the bottle upright, out of direct sunlight, and somewhere reasonably cool, heat and UV both degrade flavouring and nicotine over time, dulling the taste faster than the bottle would otherwise fade. Store it out of reach of children and pets; the child-resistant cap is there for a reason, and nicotine-containing e-liquid is genuinely harmful if swallowed. Once you've added a nic shot and shaken the bottle, try to use it within the timeframe printed on the packaging, mixed e-liquid doesn't keep indefinitely, and flavour is usually the first thing to go before the nicotine itself degrades.

FAQ

Is Seriously Fusionz a nic salt or a freebase e-liquid?
As a shortfill, it's supplied to be mixed with nic shots to reach your chosen strength. Check the bottle and any shots you pair it with to confirm which type you're using, since salt and freebase nic shots behave differently in terms of throat hit.

Why does my vape taste burnt after switching to this flavour?
It's almost always the coil, not the liquid. A burnt taste means the wick has run dry at some point, either from under-priming a new coil or letting the tank run low. Swap the coil and prime it properly before judging the flavour.

Can I mix Cherry Sour Raspberry and Fantasia Grape flavours together?
You can, though results vary by taste. If you want to experiment, do it in a spare tank first so you're not committing a full bottle to a blend you might not like.

How many nic shots does the bottle take?
Follow the fill-line and instructions printed on your specific bottle size, since shot ratios are set to hit the correct final strength for that volume.

Is this suitable for a first-time vaper?
It's better suited to vapers already using a sub-ohm tank or higher-power pod system. If you're switching from smoking and haven't vaped before, a simpler starter kit with a pre-mixed nic salt liquid is usually an easier entry point.
