I started using BumGenius 3.0 diapers but had a friend that gave raving reviews for this one. I bought two of them to try and was not impressed at all. They leak. I did get the seconds but I'm sure they wouldn't sell something so off from the perfect product that they would jeopardize their reputation. They work though and I hope that when my child is a bitt bigger that he can use these more. He is only 15 pounds and I got mediums they are a bit big around the legs.
