Query: I READ THE INSTRUCTIONS- and WOW still leaked.

I had these bottles (which are quite pricey) when my daughter was born. These are what I registered for because everyone said they were the best. I am just telling you that after a few months, I dumped these for much cheaper bottles. I DID read instructions, I did call and email Avent for guidance. I am not a moron, I know how to assemble a bottle and I did go step by step with them and still, leaks. Before buying these, just ask yourself "If I have to read detailed instructions to put a bottle together, and it still might leak, is it really worth it?"Trust this experienced mom. It's not.
