I'm going to admit immediately that this flavor profile seemed interesting but I'm only familiar with apple and key lime, so I wasn't sure what to expect. There's a small throat hit but it's not unbearable and it produces pretty nice clouds.
It isn't a super sweet liquid and the flavors are pretty light and floral. The initial inhale, to me, was kind of reminiscent of an unsweetened green tea with hints of fruit. Tasting it now, though, the apple comes in very faintly at the forefront followed up by a very vague cooling feel- I can only assume that it comes from the guava. On the exhale there's a small bright burst of key lime. The floral taste does come in somewhere in between the cooling feel and the key lime. The passion fruit, I suppose.
All-in-all, it's not an unpleasant vape. It's very delicate and if you're expecting something like a key lime pie, don't. It isn't that kind of vape. It is pretty complex and it lingers but it doesn't taste terrible if you're into that sort of thing. I can't say I'm particularly fond of light vapes like this, personally though. I wouldn't rate it badly and I would recommend you try a small bottle for yourself. It's pretty hard to describe- for me at least.
