I see a lot of reviews where people are complaining of nipple collapse. The nipple is made to collapse, so it mimics breast feeding. Milk still flows when the nipple is compressed. I used these for pumping and bottle feeding both breast milk and formula for two kids. Both of my kids took a bottle for two years and they are still in great shape. Highly recommend.

Good for the most part...
These are great because they go from attaching 2 the Medela pump 2 the freezer 2 attaching a nipple. Problems are that after a couple of months the nipple would collapse as baby would drink. Maybe the next size nipple would work but baby was still only taking 4 oz so a bigger bottle wasn't needed. Even though I always hand washed them, the markings on the side are rubbing off. If supplementing w/ formula it is almost impossible 2 dump a scoop of formula in because of the narrow opening.
