I bought this product because in the description it was written that it was the 330 ml bottles with nipples 3 holes. I received the bottles but it turns out that there was a hole. So I contacted customer service and explained the problem. I had to return the bottles and they sent me others without checking so I still found myself with two teats 1 hole and 2 bottles of 330 ml. I think the problem comes from amazon but Philips could check before sending at least the 2nd shot. So I returned everything, I was refunded and I bought elsewhere bottles of 330 ml 3 holes. But I just read they put the title "330 ml bottles 1 hole" and the description "330 ml bottles 3 holes" So in my opinion should be wary. Otherwise I like amazon usual but this time the me somewhat disappointed !!!
