Hayati Pro Ultra Plus 25000 Prefilled Pod Kit – Blueberry Raspberry/Mr Blue

Some flavours are built for a single pod, gone in an afternoon. Blueberry Raspberry Mr Blue on the Hayati Pro Ultra Plus 25000 isn't one of them. This is a big, bold blue candy flavour loaded into a device meant to run for thousands of puffs, so the real question isn't just what it tastes like on puff one, it's whether it still tastes that good much later on.

Breaking down the flavour

Mr Blue leads with exactly what the name promises, that unmistakable blue raspberry candy taste everyone recognises from slushies and freeze pops, sharp, sweet and slightly artificial in the best way. Real blueberry sits just behind it, adding a rounder, deeper fruit note that stops the whole thing from tasting like sugar alone.

There's a texture to the sweetness too, it feels thicker and more syrupy than a natural fruit vape, closer to the way a blue slush actually coats the mouth. That's not a flaw here, it's the point. A more restrained, natural berry liquid would undersell what Mr Blue is trying to do, which is recreate that specific childhood memory of a bright blue drink rather than anything you'd find growing on a bush.

As the vape opens up in the mid draw, the raspberry edge sharpens. It's tart without being sour, more of a candy tartness than a fruit acid one, and it plays well against the smoother blueberry underneath. There's a slight cooling drift on some hits too, nothing aggressive, just enough to keep the sweetness from tipping into syrupy territory.

The exhale is where the two berries properly merge. What started as blue raspberry candy up front and blueberry underneath comes out as one rounded, fruity sweet cloud on the way out, with a light candy tang lingering for a few seconds after. It's a satisfying finish rather than a sharp one, the kind that makes you want the next pull rather than needing a break from it.

Who it's for and when it hits best

This flavour suits anyone who wants a genuinely fun, candy forward vape rather than something subtle or grown up tasting. It's a strong match for social settings, nights out, gatherings, anywhere a bold, sweet flavour fits the mood better than a delicate one.

• Evenings out or long social sessions, where the device's puff count matters as much as the flavour
• Anyone switching from disposables who wants that same instantly recognisable blue candy taste but in a longer lasting kit
• Vapers who prefer fruit flavours with real sweetness rather than the more tart, natural tasting berry liquids

It's less suited to anyone after a subtle, all day background flavour, this one is upfront and stays that way, which is exactly the point.

Group settings tend to bring the best out of it too. A loud, familiar flavour like this one is easy to pass around or talk about, in a way a more understated tobacco or menthol vape never quite is. If you're the type who likes a flavour that gets a reaction, this is built for exactly that moment rather than a quiet solo vape at a desk.

Comparing it and keeping it fresh

Against a plain blueberry flavour, Mr Blue is louder and sweeter, with that candy raspberry element pushing it further from anything you'd call natural fruit. Against a raspberry forward liquid on its own, the blueberry here softens the sharper edges, so it's more rounded than a straight raspberry vape tends to be.

Because a big puff device is built for the long haul, palate fatigue is worth planning for from the start rather than after a week of vaping the same thing. A sharper, more sour flavour or a straightforward menthol kept as a backup gives your tastebuds a genuine break, then coming back to Mr Blue tends to hit just as hard as it did on day one. Rotating rather than running one flavour continuously for the full puff count is the difference between a flavour that stays exciting and one that quietly fades into the background.

A couple of practical notes

• The flavour is usually at its most vivid in the first third of the device's life, as with any big puff kit, expect a gradual mellowing as it nears the end rather than a sudden drop
• Slower, steadier draws let the blueberry and raspberry separate properly, rushing the puff tends to blur the two into one generic sweetness
• Keep the device upright and somewhere that doesn't get hot, direct heat on the pod thins the liquid and dulls the candy notes faster than normal use would

Blueberry Raspberry Mr Blue, answered

Does the flavour fade before the puffs run out?

Like any prefilled device, the taste is strongest early on and eases gradually as it nears the end of its life. It's a gradual mellowing rather than a sudden change, so you'll usually get plenty of warning before it's time to move on.

Is Mr Blue closer to blueberry or raspberry?

It's a genuine blend rather than one dominating the other, the raspberry candy note is the loudest on the first inhale, while blueberry rounds things out through the middle and the exhale.

Is this a good flavour for someone new to big puff pod kits?

Yes, it's an easy, familiar taste for anyone coming from disposables, and the strengths available are the standard nic salt range up to 20mg/ml, for over 18s only.
