I bought the bottle for kindergarten beginning of my son and I am totally satisfied. He loves them dearly and drinks since a lot more. I must say that I as only non-carbonated water pure giving. It is dense, it is not reporting, it is robust, good quality! The Mouthpiece is very practically solved, at the beginning, it took a little while, because of the handling of sucking, but is now running great! Super wrist strap! He takes mitlerweile even to bed! :)) I can only recommend ... PS they did in blue
