To be honest, the disposable vape market in the UK has been a bit of a rollercoaster lately. You’ve got established heavy hitters like Lost Mary holding the fort with their BM600 and QM600 devices, Elf Bar carving out their niche thanks to their solid legacy, and now there’s a new challenger pushing to shake things up: Hayati Vape. If you’re scratching your head wondering which big puff disposable vape to grab — the Hayati Pro Ultra or the Crystal Pro Max — then this detailed head-to-head is for you.

Setting the Scene: Why the Big Puff Market Is Buzzing
Ever wonder why big puff disposables are blowing up right now? It’s simple. Convenience, decent flavour, and decent nicotine hit with little hassle. For many in the UK vaping community, devices like the Hayati Pro Ultra and Crystal Pro Max represent the sweet spot between portability and punchy satisfaction, especially as these devices come packed with nic salt — which means a smoother throat hit even at higher nicotine levels.
Lost Mary has kept a tight grip on this segment with their BM600 and QM600 models, trusted by many for reliability and flavour consistency. Meanwhile, Elf Bar, despite numerous copycats flooding the market, still commands respect with its tried-and-tested formula; their classic flavours often set the benchmark new brands try to match.
Introducing Hayati Vape — The New Challenger
Hayati might be the new kid on the block in the UK disposable scene, but they’re no novices. They’ve recognised what the market wants: larger wattage outputs, bigger clouds, but without the bulk or the usual battery issues that plague cheaper knockoffs.
Their Pro Ultra model is being touted as a premium alternative to Lost Mary’s dominance. They’re packing in a mesh coil inside, which you know what really annoys otsnews me — it’s a detail brands often hype without delivering. But Hayati’s mesh coil design genuinely amps up flavour production and vapor density, resulting in smoother, tastier hits.
Crystal Pro Max: Sturdy, Familiar, and Crowd-Pleasing
The Crystal Pro Max stands as one of the stalwarts in this arena. It's a bit less flashy than the shiny marketing Hayati’s packing but it’s steadfast if you want consistency and no surprises. Featuring a nicotine salt blend, it delivers a throat hit that satisfies without the harshness that can come from freebase nicotine in some disposables.
Though it doesn’t always scream innovation, what Crystal Pro Max lacks in wow-factor, it makes up for in reliable performance and a more wallet-friendly price point—around £4.99 if you shop smart.
Why Nic Salt and Mesh Coil Matter—The Not-So-Secret Ingredients
Nicotine salt (nic salt) has been a game-changer in the disposable market, especially for these high puff count devices. It allows for higher nicotine concentrations without the all-too-familiar harsh throat hit you’d get from standard nicotine. This makes devices like the Hayati Pro Ultra and Crystal Pro Max easier to vape all day long.

Now, mesh coils aren’t just a buzzword tossed in to glam up specs. If you’ve used older coil tech, you’ll notice flavour can be weak or slightly muted. Mesh coils, with their larger surface area, heat e-liquid more evenly, giving you richer flavour and better clouds. Hayati’s use of mesh coil technology in the Pro Ultra definitely ups their flavour game, putting them inches ahead of Crystal Pro Max, which still rocks a traditional coil setup.
Direct Flavour Showdown: Who Does 'Blue Razz' Best?
The 'Blue Razz' flavour is a staple in vape shelves and rightly so — it’s tangy, sweet, and refreshing. Lost Mary nailed it years ago in their BM600 model and many customers swear by it. So, when Hayati and Crystal put their spin on Blue Razz, the question is — who’s delivering the authentic experience?
Device Flavour Accuracy Vape Smoothness Cloud Production Overall Score (out of 10) Hayati Pro Ultra Bright, tangy, and vibrant. Hints of sharp raspberry with subtle blueberry sweetness. Very smooth thanks to nic salt and mesh coil combo; no throat irritation. Dense clouds, impressive for a disposable. 8.5 Crystal Pro Max Good but diluted; leans more on artificial sweetness. Decent smoothness, typical of nic salt disposables. Standard cloud output, nothing special. 7Verdict: The Hayati Pro Ultra nails Blue Razz flavor complexity; Crystal Pro Max is good if you prefer milder tastes.
You Know What Really Annoys Me? Fake Vapes and Dodgy Corners Shops
Listen, if you’re tempted to save a quid or two by buying cheap disposables from dodgy corner shops, think twice. Counterfeit vapes are everywhere, and they’re not just ripping you off — they can be downright dangerous. The airflow might suck, the battery will underperform, coils taste burnt, and some even leak juice like a bad tap.
Elf Bar fakes flooding the UK market set the precedent: great brand recognition attracts scammers. You often pay similar prices (~£4.99) but get a fraction of the puff count and a grossly inferior vaping experience. Hayati’s official website and trusted UK retailers are your best bet to avoid this headache.
So, What's The Verdict? Hayati vs Crystal Vape
If you’re hunting for the best big puff vape alternative to Lost Mary and Elf Bar, here are the things to consider:
- Flavour & Smoothness: Hayati Pro Ultra takes the edge with its mesh coil tech and crisp flavour profile. Price: Crystal Pro Max usually lands cheaper around £4.99, making it attractive if you’re budget-conscious. Brand Trust: Lost Mary and Elf Bar still hold strong reputations. Hayati is rising fast but still building that legacy. Durability & Puff Count: Both perform well, but Hayati promises slightly higher puff counts with more consistent hits.
Final Thoughts From a Former Vape Shop Manager
Having spent years behind the counter, I can tell you one thing — smart vapers look beyond shiny boxes and boardroom marketing. If you want flavour and reliability in a pocket-friendly disposable, Hayati Pro Ultra is doing a better job than most in 2024’s crowded market. Crystal Pro Max is no bad shout for a quick fix, but don’t expect fireworks.
Just remember: always buy from trusted retailers, avoid the dodgy corner shop deals, and be wary of too-good-to-be-true '£4.99' prices online — sometimes you really do get what you pay for.
At the end of the day, whether it’s Hayati, Lost Mary, or Elf Bar, it’s about finding a flavour and feel that suits you—as big puff disposables become the norm rather than the niche.
