Really awesome toilet, such a change from the old, short, round toilet that was there before. Installed it myself (we were two gals) using two 2x4s to position it on top of the flange, and then slowly remove each 2x4 to ensure we hit the screws and the wax correctly. Had it since March and it uses very little water but is powerful. My other toilet gets water stains immediately, while this one looks nice and clean for a long while.
