Fortunately, before I purchased I read through enough reviews of these k-cups to discover that they add some artificial sweetener to them along with sugar.  I'm shocked that the item descriptions don't make this clear.  I consider that important information!  I decided to give them a try, anyway, considering some reviewers thought it was hard to tell.  I realize that many products do this recently, but they usually fall short of hiding that nasty aftertaste.  Sadly, this one does too.  It's close - I can almost enjoy a cup - but it's still unmistakable, especially if you don't consume much artificial sweetener.  (I chew sugar-free gum, and that's it for me.)  It's a shame, too, because the chocolate flavor is nice.  In fact, I rated these a 3 simply because my son tolerates the sweetener enough to drink them.  And I was really jazzed about the caramel cappuccino before I found out about the sweetener...but now I won't be buying any.  (Side note: many cappuccino reviewers complained that they're instant coffees that taste like gas station cappuccino - that would be fine with me, if it weren't for the artificial sweetener which those gas station cappuccinos don't have.)  If they begin to offer a line without the artificial sweetener, I'd buy it, but until then I'm staying away from Grove Square products.

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.

I ordered this item in a large quanity, but wanted the items packaged as shown.  They were for favors in a holiday bag for the company employees.  When they arrived a few were packaged as shown but the bulk were loose.  If I had know they would come like this I would have gone to COSTO or some other discount store for the purchase.  The cute little box that would have helped make them special and what I thought I paid for was missing.
