I used Avent bottles for both of my children.  I received my first Avent bottle in a sample pack from Babies R US. From then on I was hooked. I have never used any other. I have had great success with them I did buy the wrong size nipples so I had some leaking. I like the fat bottles they are easy for my son to hold onto. I like that they are BPA free.  I had a breast pump for when I was nursing and the bottles were interchangeable. I like the price the best! A lot of bottles are not worth paying high prices for. I think Avent are priced nice for what they are worth. I have never had any trouble...
