Title: They just work.
Review: I tred Avent and others and switched to Dr. Brown/s. there's a reason they're patented. They work. No more gas pains or air bubbles. amazing. Yes, more peices, but so what, my babys comfort (and yours too) is well worth it . They do leak occasionally, but if you don't overfill and don't tip them up too high when feeding, When heating the milk don't leave the top tight, loosen it, then tighten it to feed or it can leak. they'e great!
