Works great!
I bought 2 of these toilets to replace the main ones in our house with a lower gpf. They work well. The first one was very easy to install. The second one has been a little harder - we are having a hard time getting the toilet level despite all the usual adjustments.

Great look & easy enough to install but It won’t refill itself half the time even after a lot of adjustments & sometimes keeps running because the piston won’t set completely level. I really hope the second one doesn’t have these issues.
