Query: Pretty good bottle

These bottles are pretty good. The nipple is a little large and seems to flow kinda fast for my breastfed baby. She makes quite a mess while drinking from these. However, the bottle is nice and durable. The nipple and caps fit snug. Also, they work great as breast milk storage containers. You can take out the nipple and put the insert in the cap for freezer storage. I like that. My daughter doesn't get a bottle often, but when she does this in one of the types I use.
