The only bottle that keeps the water cold during our walks in the scorching heat and the hot tea warm all night during our colds! I have had it for 2 years now and I will get another one for my kids. The only negative thing I found is that the designs on it started to wear off very quickly after purchase.

Very beautiful, without leaks but despite its constant and thorough washing, there is a very unpleasant metallic smell in its mouth which does not go away even with baking soda!
