This is now the second cup, which I bought for my son. My son always had problems, despite Flaschenkind to drink something else besides milk. In the summer, it was really funny nciht and I looked around for alternatives to suction bottles and wanted to actually buy the similar cup from Avent. However, I came across this one, with several comments, this is better than that of Avent. Now I can not compare, but I can say that both I and my son loves this mug !!! it works really well and he has already had good out with 5 months, how to drink out of this mug. The cup is really tight. Of course - if he is thrown from the chair, then squirts also not a little out ... but in normal use it is tight. It does not drip after it and nothing works out, where it is not supposed to get out ... The cup comes with a cover, this is very hard on it and again, ... I have the cover simply put on the shelf, ... because it is warm and dry and I do not need him anyway, because the cup up close is. Cleaning is also great, ... Another plus point is that it is for it, unlike other cups, you can buy replacement parts. The silicone rings I've recently also bought. cheaper than n new cup to buy All in all a great part and worth every penny !!!! TOP
