Hayati Pro Ultra Plus 25000 Prefilled Pod Kit – Blueberry H'Bubba/Watermelon H'Bubba

Two flavours, one device, zero compromise

Blueberry H Bubba and Watermelon H Bubba isn't a single flavour so much as a pairing designed to work off each other. "Bubba" here is short for bubblegum, and the "H" points to the hybrid style blend, meaning each side is already a two part flavour before you even switch between them. Blueberry H Bubba gives you a rich, slightly musky berry wrapped around sweet bubblegum, while Watermelon H Bubba does the same trick with a juicier, sharper melon instead of the berry. Having both loaded into the Hayati Pro Ultra Plus 25000 means you're never locked into one mood for the whole day.

Blueberry H Bubba: the taste breakdown

On first inhale, the blueberry lands first and it's a proper deep, almost jammy berry note rather than the thin, sharp blueberry you get in some cheaper mixes. There's a small tartness at the very front that fades fast, replaced by the bubblegum coming through underneath. By the middle of the vape, the two have merged properly, so you're not getting "berry, then gum" in stages, you're getting a rounded, sweet, slightly chewy sensation that still tastes recognisably fruity rather than purely like candy. The exhale carries a soft, sugary bubblegum trail with the blueberry lingering just behind it, and it fades gently rather than cutting off abruptly.

Watermelon H Bubba: the taste breakdown

Switch over and the whole character of the vape changes. Watermelon H Bubba opens brighter and juicier, with that unmistakable fresh melon flesh note hitting first, slightly sweeter and less sharp than a straight watermelon flavour on its own because the bubblegum is already softening the edges from the very first draw. Through the middle of the puff it stays lighter than the blueberry side, more refreshing and less dense, before settling into a candy sweet finish on the exhale. Where blueberry bubba feels rounded and a bit indulgent, watermelon bubba feels crisper and more thirst quenching, even though neither one is actually a menthol or ice flavour.

Who this pairing suits, and when to use which side

This dual flavour setup suits vapers who get bored fast and don't want to carry two separate devices to avoid it. Rather than committing to one profile for the full 25000 puffs, you get a built in reset button. It's particularly good for people who like sweet, dessert adjacent vapes but find a single all day bubblegum flavour a bit much by the afternoon.

• Blueberry H Bubba works best later in the day, evenings especially, when a richer, more rounded flavour feels satisfying rather than sickly
• Watermelon H Bubba is the better choice earlier in the day or after eating, when a lighter, juicier profile sits easier
• Switching sides mid session is genuinely useful if you notice the sweetness building up on your palate, since the two flavours reset each other far better than repeating the same one

How the pair compares to single flavour bubblegum vapes

Standard bubblegum flavoured e-liquids, without a fruit paired in, tend to taste one note the whole way through, sweet from first inhale to last exhale with nothing else developing. What makes both sides of this device more interesting is that the fruit does actual work rather than just sitting on top as an afterthought. Compared to a plain blueberry vape, Blueberry H Bubba is noticeably sweeter and less sharp, since the bubblegum rounds off the tart edges blueberry usually carries. Compared to a plain watermelon vape, Watermelon H Bubba trades some of that clean, almost watery freshness for a candy sweetness that makes it feel more like a treat and less like a palate cleanser.

If you're coming from fruit only liquids and haven't tried a bubblegum hybrid before, expect a noticeably sweeter overall experience on both sides. It's a different category of flavour, closer to dessert vapes than straight fruit ranges, even though the fruit is doing most of the talking in the first few seconds of each puff.

Rotating to avoid palate fatigue

Even with two flavours built into one kit, palate fatigue can still creep in after enough puffs, particularly because both sides share that underlying bubblegum sweetness. The fix is simple: use the switch deliberately rather than only when you remember to. Some vapers set a rough rule, blueberry in the evening, watermelon during the day, and stick to it so the palate never gets more than a few hours on one profile. If you find both sides starting to taste flat by the end of a long day, a short break from vaping entirely, even fifteen minutes, resets your taste buds more effectively than switching sides again.

Getting the truest taste from each side

• Take slower, longer draws rather than short sharp puffs. Both hybrid flavours need a moment to develop from the initial fruit note into the fuller bubblegum finish, and rushing the draw shortchanges that
• Store the device upright and away from heat, since bubblegum flavourings in particular can taste slightly different if the liquid has been sitting somewhere warm
• If one side starts tasting muted before the other, it's usually just down to which flavour you've been favouring, not a fault, so give the neglected side a proper run to compare fairly

Blueberry and Watermelon Bubba FAQ

Can I use both flavours whenever I like, or do I need to finish one side first?

You can switch between Blueberry H Bubba and Watermelon H Bubba whenever you want, puff to puff if you like. There's no need to empty one side before trying the other, which is the whole point of having two separate flavours built into a single kit.

Why does the bubblegum note taste different on the blueberry side compared to the watermelon side?

Each side is blended as its own complete flavour rather than the same bubblegum base with two different fruits dropped in. Blueberry's natural depth pulls the bubblegum toward a richer, chewier character, while watermelon's lighter juiciness keeps its bubblegum pairing brighter and less heavy.

Which side is sweeter?

Blueberry H Bubba generally reads as the sweeter and more rounded of the two, while Watermelon H Bubba, despite still being a bubblegum blend, comes across as fresher and slightly less sugary because of the lighter fruit underneath it.
