Query: Didn't work for me!

It sounds like a great idea but it didn't work for my toilet. I spent Tuesday morning installing this thing. The bottom of the toilet leaks like a sieve. I am very disappointed. I will be installing a wax ring this evening. It is a nasty enough job doing it once. To have to go back and do it again is leaves me with a very disgusted feeling.
