We bought two identical ones. The first one tore at the opening from the baby's bite, the same with the second one. It tears so easily, unacceptable and very dangerous.

While it seems like an excellent product, for some reason my baby has not been able to drink water yet! We tried for a whole month... he doesn't seem to get used to it... on the contrary, he manages very well with any other bottle he drinks from! I don't know what the problem is, maybe the material is quite "hard". To confirm it, I tried to drink water myself and it required quite a bit of "sucking"... I opened the nipple holes a bit... nothing! It's a shame because the company has great educational bottle designs!

Very good for my daughter at the age of 10 months when she first drank milk outside breastfeeding. The handles help a lot for her to learn to hold it! However, there is an issue with the spout as it folds and often needs to be unbuttoned to return to its original position. Overall, very good!
