I have both the 5oz and 8oz bottles. They are great to pump , store and feed from. I hate the nipples though! When my daughter is drinking the nipple always collapses on her, so I constantly have to pull the nipple out of her mouth to let air in. I wish the nipple was vented. We had to buy nipples that were vented (different brand). I love that these bottles hold up so well and do not scratch easily inside when washing. My 5 oz set of my from son, 4 years ago. They come with caps, lids, nipples and a cover for the nipple.
