Very good quality. The plastic at the spout is peeling off, posing a risk of the baby swallowing pieces. Unfortunately, it is not worth the money at all.

Amazing product for transitioning from bottle to the next stage. Tremendous valve that never leaks.

I generally trust MAM products. The cup, due to its handles, is easy for the child to use. It may be a little difficult at first, due to the relatively strong flow, but my child quickly got used to it. I have been using it for months and it hasn't had any issues. The only negative thing is that if it falls, while the child is using it, there is no way to stop the flow of water.
