havent seen any good ones Review

This is a great bottle with lots of versatility. It attaches to the Isis Manual breast pump and storage containers, transforms into a sippy cup with handles and seems to please baby with the nipple contour. They can be used for the very small newborn till your child is big enough to use as a sippy cup. My only problem with these bottles is that they leak. Unless you perfect the art of tightening the lid just right, they leak all over. I've dumped the contents of many bottles all over myself and my children. After 2 kids and thousands of breastmilk and formula bottles, I still haven't perfected the lid tightening. Too tight, they leak. Too loose, they leak.

But, I thought they were a great bottle with lots of options. Although they're more expensive than some bottles, you can get much longer use out of them by adding the handles and sippy cup lids. Despite the leaking, I bought these again for my second child.
