This was a weird drink - I had high expectations, but the flavor was just odd - it really did taste like fizzy Tang drink mix.  However, my kids really liked it, and I think it is a great alternative to junky soda, so I will most likely buy more - but not for ME to drink.  ;)

I'm so dissapointed these are unavailable right now! I LOVE these crackers with cream cheese - it's my favorite snack! I hope they become available again soon! I can't find them anywhere!

Last summer, our family discovered <a href="http://www.amazon.com/gp/product/B001CC734G">Izze Sparkling Juice Variety Pack - 12/12 Oz Btls</a> and used them for special treats on really hot days. They were refreshing and because they did not add any sugar we could fool ourselves into thinking they were healthy (they are healthier...)  When we saw Switch, we thought we might be getting even more of the same in new flavors.  Unfortunately, these are more syrupy than the Izzy's.  At least for adults, the are less crisp and refreshing.  However, kids would of course prefer these as they are sweeter.  We also tried Watermelon/Strawberry and we liked the Kiwi Berry better.  The watermelon/Strawberry had a much more Jolly Rancher like taste. I think we are going to stick to our Izzy's I think.
