I can't say these were my favorite bottles, but they are pretty good. The biggest downside... keeping up with the extra ring, and sometimes, when you get it all put together ans shake formula, it leaks. My husband doesn't seem to notice it is leaking until half of the bottle is on my baby's outfit, hair and back. It could just be him, I seem to catch it before I feed the baby, but still, it can get kind of annoying. I will say that this helped my son with gas issues he had been having, so for that, I am willing to change s few extra outfits.
