Hi,
Just a curious question Does it work pretty good or is wasted time.
Any one installed one and using it? Comments/suggestions? Good one,
bad one?

I bought one of them. Installation was simple. But the problem is that
the toilet wasn't designed for low flow, so about 1/3 of the time,we have
to use full flush, or repeat the low flush. In my case it was a waste of
money (which is what I'm good at), although it saves some water when it
works.
