I'd never heard of this brand but they were very cheap here on Amazon and I was extremely surprised at how good the Dark Chocolate Hot Cocoa is.  Absolutely worth trying, it's really quite good.

Ex Input:
I got this drink expecting the carbonated taste combined with kiwi and berries. Well I could taste the berries but no kiwi. I did like the carbonation with real fruit juices without the added sugar but it is not low cal. I think that I liked this drink better than the tangerine drink but still is not for me. The drink is way too sweet for me to enjoy it.
