This bottle is perfect for me because it is very easy to fill and 100% tight. Especially nice on the bottle is easy Verfombarkeit of the bottle body, so that the water can push out from the bottle while drinking. So you can drink faster. When I'm thirsty, I do not want dropwise drink!
Disadvantage: Not SpĆ¼Ma-proof and unfortunately it can not break down, so always be residual water in it remains the closure. Therefore, only recommended for clear water. But for that I bought it.
