We love these crackers but getting them through the mail doesn't work - all the crackers were broken and crumbly.

I admit that I fully expected to dislike this product, and approached it with a dismissive attitude - something that's this trendy can't be any good, right? well, I was wrong. The ONE coconut water is refreshing, delicious, and just barely sweet. Really wonderful stuff. The hint of pineapple adds a little bit of acidity that enhances the basic taste of the water. i bet this would make a great summer drink too, but I only had one so I didn't get tot try that. My problem now is that it's been out of stock, so I can't get more.

The Switch Kiwi Berry drink is good tasting and all natural.  It should be emphasized that it is full-strength juice, not a "flavored water" type product.  For that reason, I found it a bit strong because I am not accustomed to drinking much juice.  The carbonation does add a bit of lightness to it though.  I like that it didn't taste too artificial.
