These bottles are great. We love them and so does our baby. They are more expensive but they are well worth it. We buy the generic brand drop in liners which work great. Our baby was breast fed until she was 4 and 1/2 months but she is 6 months now and these bottles are all we use for her formula. We've only been able to find the slow drip nipples so we started just increasing the size of the holes ourselves because she wasn't getting enough and would stop feeding due to frustration. I would recommend this bottle to anyone. It works great.
