I especially like the locking system. The bottle has a multi-part closure. Screwed to the entire closure from, they can be filled prima since its opening corresponds to nearly the diameter. The mouthpiece has a double locking. So it locked up when it pulls out completely. This is in many other bottles a problem, because the mouthpiece again pressed inward when vacuuming. That can not happen here. It also closes absolutely tight with me. Pressing the mouthpiece back into it and rotate it by 90 degrees, it is locked in this position, so that carbonated beverages, the mouthpiece can not push out. I have already tried with medium water and the bottle stays tight despite carbon dioxide. Only when you open you have to watch something because it can then violently splashing.
Ultimately, this bottle even fits in my pocket Deuter run, so I when I go by bike to the running club, only one bottle for all systems need.
The white paint my bottle is so far very resistant and not scratched. Also, the cleaning with a bottle brush works with the large opening and optimal hygienic. Therefore, this bottle gets my full recommendation despite the high price.
