Review (4/5): Works for me! BUT DEFINETLY NOT LEAK PROOF
Works perfectly to soak/clean my retainer which is all I wanted it to do. I do have a hard time getting the inner cup to attach properly. It is not leak proof, not a big deal for me as I would not travel with it full of water anyway. Why does Amazon allow it to continue when so many people complain about it???
The Pink one is very pretty.
