Title: Frustrating bottles
Review: I know these get a lot of hype, but...I have had a LOT of very frustrating moments with these.The disposable liner is practically impossible to keep from creasing around the top which causes leaking.Also, the regular bottles come with nipples that have a lip on the inside. If it doesn't go on just right...it leaks. Sometimes it takes a good 5 tries just to get the nipple on right! UUUGGGHHH!
