It worked perfect for my toilet perfect fit

Simply, it works - the rubber is soft enough for a good fit, whereas the generic replacement from our local hardware shop did not seal well at all

FAST, CLEAR, EASY

This flapper is the exact match for my needs BUT there are so many variations on the theme that one needs to carefully sort through all of the possibilities or one could end up with the wrong solution to the problem.

Solved my problem once I replaced the original after many years of faithful flushes.
