Hayati Mini Ultra Vape Kit – Mr Blue

Mr Blue: the mystery berry everyone recognises but nobody can name

Mr Blue is one of those flavours that has quietly become a genre of its own. Ask ten vapers what is in it and you will get ten slightly different answers, and that is precisely the charm. On the Hayati Mini Ultra kit it arrives as a deep, moreish blue-berry blend with a cool, faintly aniseed edge, the kind of taste that feels instantly familiar even the first time you try it. If you grew up on blue slushies, blue bubblegum and blue sweets, some part of your memory lights up the moment it hits.

This piece is about that flavour rather than the hardware, since the Mini Ultra kit itself is simply a neat, pocketable pod device. What you are really buying into with Mr Blue is a mood, and it is a smooth, slightly moody, endlessly repeatable one.

Breaking down the draw

The inhale opens with a wash of dark blue berries. It is not a single clean blueberry, it is a rounded berry medley that reads as blueberry with blackcurrant and raspberry lurking behind it, sweet and a little tangy, the kind of jumbled fruit that classic blue confectionery always seems to be.

The middle is where Mr Blue earns its reputation. Underneath the fruit sits a cool, softly aniseed or sherbet-like note, a whisper rather than a shout, and it lifts the whole thing so it never feels flat or purely sugary. This gentle cooling is not a full menthol blast, it is more of a smooth, slightly minty freshness that rounds the edges of the berry and makes the vape glide. On the exhale you get a clean, refreshing finish with the berry sweetness trailing off and a light cool tingle left behind on the breath. The aftertaste is remarkably tidy for something this sweet, which is a big part of why people can vape it all day without tiring of it.

The mood and moment it fits

Mr Blue is an evening and downtime flavour as much as a daytime one. There is something a little relaxed and easygoing about it, so it suits winding down after work, a slow Sunday, a session in front of the television, or a night out where you want something smooth and undemanding in your hand. The cool berry profile also makes it a strong choice after coffee or a heavier meal, since the freshness cuts through and cleans the palate.

It appeals to vapers who want more character than a plain fruit but do not want a proper aniseed or menthol flavour taking over. It is a middle path, fruity enough to be easy, complex enough to stay interesting. Newer vapers tend to get on with it well, and long-time vapers often keep it as their reliable, no-fuss default.

How it stacks up against similar flavours

Set beside a straight blue razz or a blue razz lemonade, Mr Blue is deeper and moodier, trading the sharp, zingy sourness for a smoother, cooler, more grown-up berry. Compared with a blackcurrant menthol, it is fruitier and less bracing, since the cooling is far gentler. Against a mad blue or blue fusion style mix, the defining difference is that soft aniseed sherbet undertone, which gives Mr Blue its signature smoothness where the others lean brighter and more candied.

To dodge palate fatigue, it rotates nicely with flavours that pull in a clearly different direction:

• A bright citrus or lemonade such as pink lemonade, for daytime contrast against Mr Blue's cooler, darker mood.
• A tropical blend like mango peach pineapple, to reset the palate with warmth and juice when the berry starts to feel samey.
• A red fruit such as strawberry raspberry, for the times you want fruit without the aniseed edge.

Because Mr Blue is smooth and cool rather than sharp, it actually resists fatigue better than most, but keeping a warmer, fruitier pod on standby stops the aniseed note from ever wearing out its welcome.

Getting the most honest version of the flavour

Mr Blue rewards a slower, longer, mouth-to-lung style draw. A gentle pull gives the berries room to unfold before the cool aniseed note joins in, whereas a short, hard drag tends to skip straight to the freshness and skips over the fruit. With a fresh pod in the kit, let it stand for a couple of minutes so the coil saturates fully, then take those first draws slowly, as they are the most flavour-rich.

The profile is at its best while the pod is well filled. As the liquid runs down towards the last stretch, the berry sweetness softens and the cool note can start to feel a fraction sharper, which is the normal life cycle of any prefilled pod rather than a flaw. When the taste thins out or edges towards dry, that is the signal to swap in a fresh one.

Storage, coil life and value

Keep spare Mr Blue pods somewhere cool and dark and stood upright, since heat and sunlight are the quickest way to flatten a berry flavour and muddy that clean aniseed finish. Treated well, the flavour stays true for the life of the pod, which is rated up to around 1500 puffs. Running the Mini Ultra as a kit and then topping up with replacement pods is the sensible long game, both for your wallet and for reducing waste, and it means you can keep a Mr Blue on rotation indefinitely without buying a new device each time.

Who should probably look elsewhere

If aniseed, liquorice or sherbet flavours are a hard no for you, even in small doses, the undertone in Mr Blue may bother you, so a clean fruit or a pure menthol would be a safer bet. If you actively want a heavy ice hit, this one will feel too gentle, since the cooling here is soft by design. And if you prefer bright, sour, in-your-face candy flavours, a blue razz sour style will scratch that itch better than Mr Blue's smoother approach.

Flavour FAQ

What does Mr Blue actually taste of?

It is a mixed blue-berry blend, mainly blueberry with hints of blackcurrant and raspberry, finished with a soft, cool aniseed or sherbet note. The result is a smooth, slightly moody berry that feels familiar from blue sweets and slush drinks without matching any single fruit exactly.

Is the aniseed note strong?

No, it sits in the background. It works more like a seasoning than a headline flavour, adding a cool, rounded smoothness rather than a bold liquorice hit. Most people who dislike strong aniseed still get on fine with Mr Blue, though a very sensitive palate might pick it out.

Is it a good all-day flavour?

Yes, it is one of the better ones for all-day use, because the clean finish and gentle cooling stop it becoming sickly the way pure sweet fruits can. Pairing it with a warmer daytime pod keeps things varied. As with all these pods, it contains nicotine and is strictly for over-18s.
