Good point. I would throw in that warranty time is vastly different
that MTBF. Wax rings I am sure last practically forever if the toilet
is stable but I'd be surprised to see a 10 year warranty on one. The
main point I guess is that it is unproven. 20 years from now everyone
or no one may be using them.
Thanks for the input, its something to consider.

Wax seals last, well forever as far as I can tell.

This new product is SOOOOOO good the manufacturer relieves itself of all
responsibility after all of 1 year.
