Crystal Pro Switch 30K Dual-Flavour Prefilled Pod Kit – 30,000 Puffs, HD Display & Mesh Coil

If there’s one device that properly caught my attention recently, it’s the Crystal Pro Switch 30K. On paper, it sounds like another high-puff kit with a fancy display and big battery, but after actually spending time with it, it’s clear this device is doing a few things very differently.

First Impressions – A Proper Step Up

Right out of the box, the Crystal Pro Switch 30K feels more premium than the average dual-flavour kit.
The size is comfortable (26 × 51.5 × 107 mm), not too bulky, and the build quality is surprisingly better than most kits sitting in this price bracket.

The HD display is crisp, properly readable in daylight, and gives you everything you genuinely need: battery, puff stats, and a visual representation of your liquid.

But the thing that makes this kit stand out straight away is the flavour-switch button.

Dual-Flavour Switching – Surprisingly Clean

Many brands claim smooth flavour switching, but not all deliver.
Here though, the button actually works beautifully.

The switch from, let’s say, Blue Razz Gummy Bear to Cherry Ice, is instant, clean, and without that awkward “mixing moment” some kits create. I didn’t notice any flavour contamination or lag, it just snaps instantly to the second flavour.

A lot of that comes from the 0.8Ω Dual Mesh Coil, which produces a warm and flavour-rich vape with every pull. What impressed me most is the consistency: you don’t suddenly lose flavour after a few thousand puffs. It stays surprisingly punchy.

30,000 Puffs That Actually Feel Realistic

Now, of course, puff counts always depend on how you vape. But with 22ml total e-liquid (2ml pod + 10ml auto-refill on each side), the 30K claim doesn’t feel unrealistic.

The auto-refill chamber is one of the best parts of this kit. You don’t feel like the device is drying out mid-puff, and the flavour delivery stays steady.

The 850mAh battery won’t last you days, but with Type-C charging, getting back to full power is quick enough. It’s more than sufficient for a heavy day of use before you need a top-up.

Visible Liquid + Display – Genuinely Helpful

Another thing I appreciated while testing:
The visible tank section.

It takes away the guesswork.
A quick glance and you know exactly how much liquid you’ve got left. Combine that with the HD screen, and the whole experience feels more controlled and less “blind” compared to most disposables.

How It Vapes – Real Experience

The airflow sits between MTL and RDL, but closer to a tighter RDL. Most UK vapers who like a cigarette-style pull with a bit more body will enjoy this.

Draw activation is smooth, no delay, no rattling, no dry hits even after extended sessions.
The coil doesn’t flood either, which is rare in dual-flavour kits.

Crystal Pro Switch 30k Flavour Range – Full Breakdown for UK Vapers

One thing Crystal Pro has absolutely nailed with the Switch 30K is its flavour catalogue. It’s not just long, it’s actually well-balanced. Whether you’re into sweet candy blends, icy fruits, bubblegum profiles, or clean minty notes, every type of vaper finds something here.

1. Blue Series – Sweet, Punchy & Proper Crowd-Pleasers

Crystal Pro always dominates the blue category, and this device is no different.

• Blueberry Raspberry / Blue Sour Raspberry
  A bright, juicy pairing with a sharp sour edge on switch. Perfect for all-day use.

• Blue Razz Gummy Bear / Blue Razz Cherry Ice
  Thick, candy-sweet clouds with an icy finish. Switch keeps things from getting too sweet.

• Mr Blue / Fizzy Blueberry
  Mr Blue remains one of the most balanced mixed-berry ices; Fizzy Blueberry adds that soda pop twist.

• Blueberry Cotton Candy / Raspberry Cotton Candy
  Smooth, soft, carnival-sweet — not overpowering, but very moreish.

• Blueberry Cherry Cranberry / Blueberry Kiwi
  More refined fruit mixes with a slightly tangier profile.

• Blue Razz Gummy Bear (single-flavour pod)

• Blueberry Raspberry (single-flavour pod)

• Mr Blue (single-flavour pod)

These single-flavour versions deliver cleaner, more focused notes for people who prefer simplicity.

2. Strawberry & Cherry Profiles – Sweet but Balanced

If you like red fruits, this device has one of the biggest selections in its class.

• Strawberry Raspberry Ice / Strawberry Kiwi
  Light, refreshing, and not overly sugary — great for ex-disposable users.

• Fizzy Cherry / Cherry Ice
  Fizzy Cherry is properly fizzy (not chemical), and Cherry Ice gives a clean, cold finish.

• Cherry Berry / Fruit Bomb
  Fruit Bomb lives up to its name — layered and vibrant.

• Strawberry Raspberry Ice (single-flavour pod)

• Red Apple Ice / Summer Dream
  Red Apple Ice is crisp and juicy, while Summer Dream is a tropical, fizzy mix that feels perfect for summer-style vaping.

3. Bubblegum & Candy – Smooth, Fun & Surprisingly Consistent

Crystal Pro’s bubblegum notes are some of the best in the UK right now.

• Gummy Bear / Hubba Bubba
  Proper chewy bubblegum feel without being too sweet.

• Gummy Bear / Hubba Bubba (variant ranges)
  Smooth, nostalgic, and crowd-pleasing.

4. Mint & Cool Profiles – Clean, Crisp & Extremely Refreshing

For vapers who prefer something lighter:

• Fresh Mint / Menthol
  As clean as it gets — ideal for MTL vapers and ex-menthol smokers.

• Lemon & Lime / Lemon & Mint
  Zesty and refreshing. Lemon & Mint is particularly standout — cool, but not harsh.

• Lemon & Lime (single-flavour pod)

These flavours also feel lighter on the coil, giving slightly cleaner performance.

5. Tropical & Exotic Mixes – Smooth & Full-Bodied

A few underrated combos in the lineup:

• Juicy Peach / Juicy Raspberries
  The switch between soft peach and sharper raspberry is genuinely satisfying.

• Watermelon Ice / Watermelon Bubblegum
  One of the smoothest switches overall — both flavours complement each other perfectly.

• Banana Ice / Strawberry Banana
  Creamy, sweet, and surprisingly well-balanced for banana blends.

• Straw Guava / Dragon Berries 
  Exotic and slightly icy, great for those who like deeper fruit profiles.

Replaceable Prefilled Pods – A Massive Advantage

This point alone changes the value of this kit.

The Crystal Pro Switch 30K isn’t disposable.
You don’t throw away the device — you simply replace the pod, which contains:

• 2ml coil chamber

• 10ml auto-refill tank

This means:

• Cheaper long-term use

• Less waste

• More flavours to try

• A longer lifespan for the device itself

It honestly gives it a more “pod kit” feel rather than a disposable vibe.

What Could Be Better? (Honest Cons)

No review is complete without the downsides:

• The device is slightly weightier than traditional disposables.

• Heavy vapers may need one charge per day, as 850mAh isn’t huge.

• Some flavours are sweeter, so not every profile will suit MTL purists.

But none of these are deal-breakers.

Final Verdict – Crystal Pro Switch 30k Worth It?

If you’re looking for a proper dual-flavour kit that actually delivers on what it claims, the Crystal Pro Switch 30K is honestly one of the better options currently in the UK market.

It’s ideal for:

• Vapers who switch flavours often

• People who want long-lasting pods

• Anyone who prefers richer, warmer flavour

• UK users who want something more economical than disposables

With the replaceable pods, dual mesh coil, HD display, and good pricing at £9.75, it feels like one of the strongest value-for-money choices in the 30K puff category.
