Nipple collapses
For us, the MAM was a leaker. It's prone to leakage if not assembled just right, leaked in travel, and had leaked everywhere when we found our little tester had dropped it in her high chair. It has a flat shaped nipple that was overly soft and collapsed during feeding. We had to unscrew the bottle to let the air escape.
It's ability to self-sterilize in the microwave.
Wide mouth made filling easy.
Did we mention the leaking?! Plus an odd shaped, collapsing nipple that our baby just didn't go for.
