I tried them and the bottom leaks like crazy if it's not sealed and screwed on JUST RIGHT. That's a little too high maintenance for me and my hangry LO. Once she decides she's hungry, she wants that bottle yesterday lol. My LO isn't really colicky though, just gassy. We are ok with Philips Avent bottles for now. The Avent also has leaking issues from the top but not nearly as often or as much as the Mam.
We love them they have a flat nipple and it's shorter then most nipple so we have no more gag reflex with the bottles I own 16 of them yes you have to make sure they are screwed togather right I have maybe had 5 leaks in 4 months of using them the little fuss is worth it to me..
