Title: bottles were so frustrating to use-switched....
Review: WE heard these bottles were great, but boy were we in for a surprise! After using them for a week, the vents stopped working properly-even after boiling them once a week like you're supposed to do. WE called playtex and they had an answer for us right away-probably because others have had the same problem??????? Well, they were very friendly...Playtex told us to pull on the vents to open the holes before each feeding. Well, it didn't work. We had to open the bottle every few minutes during feedings to let the air out. Sucking on the nipple created a vaccuum and made the nipple collapse and nothing would come out. In tears, I went to the store and bought the playtex premium nurser with collapsable liners. MUCH BETTER! We called playtex and told them about our situation and they sent us a refund for 8 bottles and extra nipples.
