Verified Purchase(What is this?)
This review is from: Philips AVENT SCD271/00 Newborn Bottle Starter Set (Classic) (Baby Product)
I use these with the Avent Manual Breast Pump as well as for feeding my little one the expressed milk. No complaints at all really - he seems to feed fine with them (he's 3 months) and isn't anymore gassy than when I breastfeed him so they must be doing a good job!
