The bottle is great, does what the description promises the large drinking opening is initially a bit strange, but after this super. Had the feeling that the bottle is dirty not once what is the case with the cheap very often, where you can smell the plastic and take the taste of the drinks immediately. It's a "Hinkucker" looks elegant and clean. Unfortunately the sport drinking cap is not suitable for transportation since it is not watertight. Therefore, you can screw it him only after the transport. I find that impractical. Therefore, a point deduction. Recommended otherwise would buy the bottles again.
