SKE Crystal 4 in 1 Review: the Post-Ban Pod Kit, Honestly Tested

VapeFeat score: 8.4/10

The SKE Crystal 4 in 1 is the most sensible answer yet to the UK disposable ban: four prefilled pods in one rechargeable body, a simple twist to change flavour, and genuine Crystal Bar flavour recipes inside. It is not perfect. The twist mechanism can feel stiff, the glossy shell attracts fingerprints, and there is no USB-C cable in the box. But as a bridge between throwaway disposables and proper pod kits, this is the one I would recommend to most ex-disposable vapers first.

That is the verdict. The full breakdown follows.

Who this kit is for

Buy it if: you used Crystal Bar or other disposables before the ban and want the same flavours and the same zero-fuss experience without throwing a battery away every week. Skip it if: you want adjustable power, big clouds, refillable pods, or a pocket-sized device for nights out. This is chunkier than a single disposable and there are no settings to tweak.

One clarification before we start: SKE also sells a Crystal 4in1 Pro, a separate device. This review covers the standard 4in1 rated at up to 2400 puffs, so double-check the box before you pay.

The spec sheet at a glance

Treat the puff counts like a fuel-economy figure: “up to 2400 puffs” is measured under lab conditions with short draws. Longer draws burn liquid faster, as with every puff-rated device. What the number tells you is relative scale. Four pods hold 8ml, the equivalent of four old 600-puff Crystal Bars, all from one device instead of four batteries in the bin.

In the box

The box is refreshingly short on clutter: the device, four prefilled 2ml pods (flavours depend on the edition), and a user manual. That is everything.

The obvious omission is a USB-C cable. You almost certainly own several, and you will need one because the kit is rechargeable. SKE left it out to keep the price under twelve pounds: a fair trade, but worth knowing before delivery day. Loading the pods takes about thirty seconds.

Loading the pods takes about thirty seconds: lift off the mouthpiece, drop the four pods into the chamber, replace the mouthpiece, and twist until the arrow lines up with the flavour you want. Each pod is sealed and prefilled, so there is no juice to pour, no coil to prime, and no waiting for cotton to saturate. Inhale and it fires. It really is as close to a disposable as a legal pod kit can get.

Design and build

Rather than the pen shape of the old Crystal Bar, the 4 in 1 is a chunky, rounded cylinder with a keyhole-like profile: the pod chamber sits in the wider side, the battery in the other, all wrapped in SKE’s signature crystal-clear shell. It is comfortable to hold, well balanced, and lighter than it looks. The metal base adds a reassuring weight, with vent holes and the USB-C port on the bottom.

It looks good, but the finish has one genuine weakness: it is a fingerprint magnet, and the clear shell picks up fine scratches if you carry it loose with keys or coins. A soft cloth sorts the smudges; the scratches are permanent, so a pocket to itself is the smart move. Build quality elsewhere is solid for the price: nothing rattles, the mouthpiece seats firmly, and the pod chamber is sealed well enough that I never saw a drop of leaking liquid.

One honest size caveat: with four pods inside it is noticeably wider than a single disposable. If you compare it with the slimmest options in the best disposable vapes roundup, it will not win the pocketability contest. It is the price of carrying four flavours at once.

The rotating 4-pod system explained

This is the whole point of the device, and it works better than it has any right to. You twist the mouthpiece until the flavour you want clicks into position under it, with a little “click-clack” confirmation. That pod is now live; the other three sit sealed and waiting.

The switch is mid-session and consequence-free: you do not have to finish a pod before moving on. Start the morning on Lemon and Lime, get bored by lunch, twist to Watermelon Ice, and the first pod waits exactly as you left it. Each pod has its own mesh coil sealed inside, so flavours never bleed into each other and you never inherit the burnt tail of someone else’s pod. When a pod is empty, you can buy replacement 4-packs and load them in, which is where this device leaves actual disposables behind on waste.

The honest downside is the twist itself. The mechanism is stiff at first, and it never becomes one-handed effortless. You will use two hands and glance at the little alignment window to confirm the right flavour is engaged. It loosens with practice, but SKE could have made it smoother out of the box.

Flavour performance

SKE built its reputation on Crystal Bar flavour recipes, and the 4 in 1 inherits them. The mesh coil in each pod delivers clean, consistent flavour from the first puff to the last, and the draw is a smooth, tight MTL pull that genuinely mimics the old disposable. At a fixed 11W there is no way to burn a flavour with too much power, one of the underrated strengths of the prefilled category.

The kit is sold in colour editions, each containing four flavours, and replacement pods are also sold in many single flavours. The main editions are:

Flavour is subjective, so here is an honest read rather than a ranking. Lemon and Lime is the standout: zesty, sweet and sharp with a light ice finish, and the wider airflow of this device actually improves it over the old disposable version. Cola Ice is the other crowd-pleaser, fizzy and cold in a way that survives the 2ml pod without fading. The berry flavours (Blueberry Raspberries, Blueberry Peach) are smooth all-day vapes, sweet without the syrupy heaviness that ruins some dessert-style liquids. Tropical Mixed and Lychee Ice sit at the lighter end: refreshing, but less distinct when vaped back to back with the louder flavours.

Not every pod is a hit, though. Fizzy Cherry in particular has a rougher, harsher edge than its name promises, and there are scattered reports of the occasional dud pod arriving with a faint burnt taste from the start. That is the cost of sealed factory pods across every brand, but with replacement 4-packs around eight pounds, a dead pod stings more than it should. Buy your pods from a reputable shop and keep the receipt.

Battery and charging

The 950mAh cell is the quiet hero of this kit. It comfortably outlasts the liquid in all four pods on a single charge for a moderate vaper. A heavier user will likely need a top-up before the last pod is done, which is exactly where the rechargeable design earns its keep: the old disposable equivalent would have died with juice still inside and gone straight in the bin.

Charging is USB-C at a 1500mA input, and SKE’s own guidance says a full charge takes around 50 minutes. The indicator light breathes red while charging and turns solid white when done. There is no screen and no percentage readout, so battery state is always a guess between “white light earlier” and “it just died”. A simple four-bar indicator would have been a real improvement for ex-disposable users who never had to think about batteries before. Note also that the port sits on the base, so the device cannot stand upright while charging.

Running cost maths: kit vs disposables

This is where the 4 in 1 makes its strongest argument, and the numbers are worth doing properly because they are better than most people assume.

A £11.99 kit with four pods delivers up to 2400 puffs: £0.005 per puff, half a penny. A typical £5 600-puff disposable costs about 0.83p per puff. So the kit undercuts the equivalent four disposables (£20) by about eight pounds, with only one battery instead of four.

The refill economics are even stronger. A 4-pack of replacement pods at £7.99 gives you the same 2400 puffs at a third of a penny per puff. Against four disposables that is a saving of about twelve pounds every cycle, and the device keeps going because each fresh pod brings a new coil with it.

Put it on a monthly basis for a moderate vaper getting through roughly 2400 puffs a week. The disposable habit costs around £80 a month. The 4 in 1 habit costs the initial £11.99 plus about £32 a month in refill pods: roughly £44 in month one, £32 a month after. That is a saving of the thick end of £48 a month, or the best part of £600 a year, and four fewer batteries a week going to waste. Our guide to vape juice prices puts the wider liquid market in context if you ever graduate to a refillable kit, but within the prefilled world this is about as cheap as convenient vaping gets.

Puff ratings are maximums, and real-world mileage varies with draw length, but the same caveat applies to disposables. Whatever your draw style, the 4 in 1 costs roughly 40 to 60 percent less per puff than the equivalent disposables.

Who should skip it

The 4 in 1 is a specialist: prefilled, fixed power, MTL, no settings. If any of the following describes you, look elsewhere.

You want clouds or adjustable power. This is a fixed 11W MTL device with a tight draw. There is nothing to adjust and no DTL option. Cloud chasers and tinkerers will be bored within an hour.

You want one flavour for weeks. If you vape a single flavour exclusively, the four-pod carousel is wasted on you. A single-pod prefilled kit is cheaper, smaller and simpler for that use case.

You want a pocket rocket for nights out. It is chunky. The battery life makes it a great all-day device, but for a night out you will notice it in a jeans pocket.

You want the absolute maximum puff count. The 2400-puff rating is solid, but the current market has big-puff prefilled kits pushing much higher. The Geek Bar Pulse X is the heavy-hitter alternative if sheer longevity is your priority, though it plays a different game on flavour variety.

You are deciding between disposable styles generally. Our SBX vape review covers the big single-format disposable for comparison, and it is worth reading both before you commit to a pod system. And if you are switching from cigarettes rather than from disposables, our cigarettes vs vaping breakdown is the honest starting point on what to expect.

Final verdict

The SKE Crystal 4 in 1 does one thing and does it extremely well: it gives ex-disposable vapers their old experience back, legally, with four flavours on tap and a battery that does not die before the juice runs out. The flavour recipes are proven, the rotating pod system is genuinely useful rather than a gimmick, and the running costs beat disposables by a wide margin.

Score: 8.4/10. The best post-ban starter for flavour-switchers, and the easiest recommendation in the prefilled category right now.
