I've replaced flappers before in toilets but I remember
once when I

flappers at
different prices. Is there really better quality
flappers than the
norm (last longer) ? I know I can google this but like
to know what
people here think.

I was sent one of these to test.
I installed it today and is pretty good so far.
I think the warranty is 10 yrs
