Query: Did not work for us at all

This product did not work with our toilet because of the angle of the toilet bowl. There was no way of knowing this until we took it out of the box and tried to install it. We ended up with a swing-shut toilet lock from Target instead, which would probably work for a wider variety of toilet shapes. (Who ever knew there was a variety of different bowl shapes in the first place?)
