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???<br />The Pink one  is very pretty.
