Leaky waste of money

I only give this product 1 star because that is the lowest option allowed. Regardless of following instructions line by line, these bottles really do leak. All over the place. When you least expect it. Imagine having to change your baby's entire outfit in the middle of the night while he/she is screaming bloody murder for a bottle that is leaking like a sieve all over him/her. This is a reality when you buy these bottles. I can't tell you how many times this happened to me when feeding my son. I don't know who is lucky enough to get the ones that don't leak, but none of my friends who bought them were lucky either. ^M

mostly great

I have been happy with the nipples and venting of the avent bottles. The only problem I've had is that they will leak occasionally. Making sure that the nipple is damp before you screw on the top seems to help. Though he was primarily breastfed, my son had no problems switching back and forth between these bottles and breastfeeding.

These are great bottles and Amazon.com is the best for everything.
