Elux Firerose Alter 7K: Flavours, Specs & Honest Buyer's Guide (UK 2026)
Last updated: July 2026
The Firerose Alter 7K is Elux's entry in the crowded 7,000-puff bracket, and it's been generating a surprising amount of search interest for a device most shops barely explain. Here's everything worth knowing before you buy one — the real specs, the full flavour list, and an honest take on where it fits against the bigger names.
What Exactly Is the Firerose Alter 7K?
First, the naming confusion: Firerose is Elux's device line — the same Elux behind the Legend disposables and the nic salt range half the UK vapes. The Alter 7000 (usually shelf-labelled "Alter 7K") is their compact refillable pod kit, built for the post-disposables-ban market.
The headline specs, verified across UK retailers in July 2026:
- Up to 7,000 puffs per kit
- 2ml prefilled pod + 5ml refill container — 7ml of liquid in total, which is where the puff figure comes from
- 20mg (2%) nicotine salt — the UK maximum, aimed squarely at ex-smokers
- Rechargeable battery with USB-C
- Typical price: £5–£8, with multi-buy deals common — it's one of the cheapest routes into a big-puff kit
Like every legal big-puff kit in 2026, it uses the pod-plus-reservoir format: UK law caps nicotine containers at 10ml and pods at 2ml, so the "7K" comes from topping the pod up from the sealed refill container rather than one giant tank.
Firerose Alter 7K Flavours — Full List
The Alter 7K launched with around 20 flavours, and the list reads like a greatest-hits of the Elux Legend range — deliberately so:
- Mr Blue — Elux's signature mixed-berry ice, the one to start with
- Blue Crush, Blue Razz Gummy, Blue Sour Raspberry, Blueberry Raspberry, Blueberry Cherry Cranberry — the blue family, all strong sellers
- Cherry Ice, Cherry Sours, Strawberry Raspberry Cherry — the cherry corner
- Cola Ice, Fizzy Gummy, Tutti Fruity, H Bubba (bubblegum), Strawberry Watermelon Bubblegum — sweets and pop
- Fresh Mint — the menthol option
- Lemon Lime, Orange Zest, Oasis, Vim Tru (Vimto-style), Pineapple Peach Mango — citrus and tropical
The Honest Bit: Should You Buy One?
Straight answer from a shop that has sold every 7K-class device on the market: the Alter 7K is a solid budget kit, but it's competing in the most brutal bracket in vaping. For a couple of pounds more, kits like the RandM Tornado 9000 give you 2,000 more puffs, a bigger flavour range and better hardware, and the step up to a Hayati Pro Ultra 25000 works out cheaper per puff again. Our full best cheap vapes under £20 roundup ranks the whole bracket.
Where the Alter 7K genuinely wins is flavour authenticity — if you vape it for Mr Blue or Blue Razz Gummy, you're getting the real Elux recipe. And here's the money-saving secret most Alter buyers don't know: every one of those signature flavours exists as a £3-ish 10ml Elux nic salt that works in any refillable pod kit. We stock the full range in our Elux Legend nic salts collection, and our Elux flavours guide matches each disposable flavour to its bottled twin. Same taste, roughly a third of the running cost — that maths only gets better when the vaping products duty lands in October 2026.
Alter 7K vs the Competition
- vs RandM Tornado 9000 — Tornado wins on puffs, flavour count and build; Alter wins on price and pocket size.
- vs Lost Mary BM6000 — the BM6000 has the better screen and pod ecosystem; Alter is cheaper and its flavours hit harder.
- vs a refillable kit + Elux nic salts — the refillable route costs less within a fortnight and gives you the same flavours. See our beginner's refilling guide if that sounds intimidating — it isn't.
