Review on Klean Kanteen Stainless Bottle Organic by Michelle Cooper

I love the sport top! Makes it impossible to spill yourself, but drinking from it can be noisy if it makes a gurgling noise in a very quiet place like a library. I don't like that the bottom of these bottles is slightly rounded. So if they're less than half full and you hit them, they tend to fall off. Colors tend to wear off if they're in the car cup holder a lot. After 4-5 weeks of use, a ring of the same color will appear at the top of the cup holder. That may be because it's smaller than the average cup holder and tends to rattle internally. However, the company works for a good cause!
