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.

The only reason for the 3 stars was the packets the individual teas were in.  I love this tea, I have the ones in the tin on auto delivery.  I was taking a trip, and ordered these so I could take some with me on my trip.  Prior to leaving home I took some out of the box and put them in my suitcase.  I got to the hotel and tried to open the little packages.  Impossible to open the individual packages.  No knife with me, I ended up using a toe nail clipper to open the individual packages of each tea.  Hopefully this was just a problem with the first box, but I would not recommend buying this tea in the boxes, go for the cannisters.  If you do buy the boxes have something near by to open each and every packet of tea.

The first "Switch" carbonated drink I tried from the amazon vine program is the watermelon-strawberry and now, here I am trying the "kiwi-berry" flavor. I've said before that I am not a fan of carbonated drinks and this flavor just reminded me why.  There's no taste of berry nor kiwi in it, and the thing just flat out tastes like carbonated plastic. For a drink claiming to be "all natural", no sugar, or preservatives...it sure tastes quite like the opposite. Now I don't know if I just received a defective can, but it isn't it sure didn't quench my thirst and I needed to eat a "hot pocket" just to get rid of the odd after taste. Cool packaging, less than good taste.  I didn't like it! [2 Stars]
