The Watermelon OG AIO smells and tastes incredible. That sweet refreshing watermelon aroma when you first open it is so inviting and the flavour delivers completely. The deeply relaxing indica effects are heavy and satisfying. Love it.

Absolutely brilliant product. The Watermelon OG from Cake is sweet, refreshing and deeply relaxing. The indica effects are heavy and satisfying and the 1.25g size gives you brilliant value. One of the best evening AIOs I’ve tried.

Take it from me, this vape is properly the real deal. I’ve tried a lot of different brands but this specific one just hits the sweet spot. Really discreet so I can take it on walks, and the battery hasn’t died on me yet. Genuine pain relief for my lower back too. Cheers to the these guys team for sorting me out so quick.

The Watermelon OG is a seriously enjoyable evening vape. The sweet watermelon flavour is so refreshing and the OG earthiness underneath adds depth and complexity. The deeply relaxing indica effects are exactly what I needed.

Got my package from Leaflybuds yesterday. Packaging was totally smell-proof which I really appreciate. As for this vape, it hits like a freight train. Really potent, thick clouds, and an incredibly clean taste. You can tell they source quality liquid. Perfect for winding down after a 12-hour shift.
