So far so good
I had already earlier a bottle like this from amazon that leaked water after a few months without being dropped, since then I have the A5 memobottle in daily use.
This one has way better quality and with the silicone sleeve, I think dropping this bottle won't break it.
One negative point is, that the bottle easily falls over
so you have to lay it down, buy the bottle stand or be risky.
In total I'm very happy with it! :)
