Hayati Rubik 7000 Vape Kit – Blueberry Raspberry

Blueberry and raspberry is one of those pairings that sounds obvious until you actually taste a version that gets the balance right. Hayati's Rubik 7000 does exactly that, treating blueberry as the deeper, slightly savoury base note and letting raspberry bring the sharper, brighter edge on top. It is less of a smoothie style blend and more like two distinct berries taking turns, which keeps the flavour interesting well past the first few pulls. Nothing about it feels rushed or overly sugared, which is fairly rare for a two fruit combination pitched at this kind of everyday, all day vape.

What You Get on the First Pull

The opening note is blueberry, and it leans towards the deeper, almost woody side of the fruit rather than anything overly candied. There is a slight skin like bitterness in there, similar to biting into a fresh blueberry rather than a syrup, which grounds the whole flavour before the raspberry has a chance to show up. It is a calmer start than a lot of berry vapes go for, and it works in this flavour's favour.

Halfway Through, Raspberry Steps In

As you settle into the vape, raspberry starts to lift the flavour, adding a tart, slightly seedy brightness that cuts through the blueberry's roundness. This is really the flavour's best stretch, the two berries sitting side by side rather than merging into a single generic berry note, so you get the depth of blueberry and the sharpness of raspberry at more or less the same time. There is a light sweetness running underneath both, enough to stop things tasting sour but not enough to turn it into a dessert flavour.

The Finish

Exhale is where the raspberry pulls slightly ahead, leaving a tart, faintly seedy aftertaste that fades fairly quickly rather than clinging to the palate. It is a clean finish overall, with just a whisper of the blueberry's deeper note left underneath, which makes the flavour easy to vape back to back without it turning heavy or sickly.

When and Who This Flavour Works Best For

If you like your fruit flavours to taste like actual fruit rather than fruit flavoured sweets, this is a strong option. It suits vapers who find some berry vapes too sweet or too artificial, since the balance here stays closer to real fruit than candy. Time wise, it works well in the morning or early afternoon, when a brighter, fresher flavour suits the mood better than something rich or dessert like. It is also a solid warm weather flavour, the kind of thing that feels right on a summer afternoon rather than needing a cold evening to make sense. Vapers who tend to switch off dessert style flavours once the weather warms up often find this one fills that gap without tipping into anything too sharp or sour.

How It Stacks Up Against Other Berry Vapes

Compared with a straightforward mixed berry flavour, this one is more clearly defined, you can pick out blueberry and raspberry separately rather than tasting one blurred berry note. Against a strawberry led flavour, it reads less sweet and more tart, with none of the candied edge that strawberry vapes often lean on. Set beside a blackcurrant flavour, blueberry raspberry feels lighter and brighter, blackcurrant tending to sit deeper and slightly more medicinal by comparison.

Because the flavour stays fairly consistent throughout a session, it is worth switching things up occasionally so it does not become background noise. A few flavours that pair well in rotation:

• A citrus flavour like lemon or grapefruit, for contrast against the berry sweetness
• A menthol or ice flavour to reset the palate between sessions
• A tropical flavour such as mango or pineapple for something at the opposite end of the fruit spectrum

A Couple of Tips for Getting the Best Out of It

With a refillable kit like this, the flavour tends to taste most vivid in the first day or two after filling, so if you notice the berry notes fading, a fresh fill usually brings them straight back rather than pointing to any real problem. Letting the coil soak for a few minutes after refilling, rather than vaping immediately, helps avoid a dry or burnt note that can mask the fruit underneath it. Storing your e liquid somewhere cool and out of direct sunlight also helps keep both berry notes from fading over time, since heat and light are the main things that dull fruit flavours in general. As always in the UK, nic salt strengths top out at 20mg/ml, and this is an adult product for over 18s only.

Blueberry Raspberry: Quick Questions

Does it taste more like blueberry or raspberry?

Blueberry leads on the inhale and raspberry takes over on the exhale, so neither fruit fully dominates, though which one stands out most can vary slightly from person to person.

Is it a sweet flavour or a tart one?

It sits closer to tart than sweet, especially compared with candy style berry vapes, though there is enough natural sweetness underneath to stop it tasting sharp.

How long does the flavour stay fresh after filling?

Most vapers notice the clearest, brightest version of the flavour in the first day or so after a fill, with the fruit notes gradually softening as the liquid in the tank runs down.
