Terrible bottles

I was so excited to use these bottles as I heard so many good things about them but was very disappointed when every time I used them they leaked. I also had some ineffective nipples, some had very little flow and some had very fast flow and almost choking my son.

I received these bottles as a baby shower gift. My baby had very bad colic and these bottles seemed to help a little. I did find all the small pieces that needed to be cleaned and sterilized very time consuming. Also, these bottles did poorly in the bottle sterilizer and often leaked. I wouldn't recommend these bottle.
