Bests & Worsts Reviews from Amazon

It gives good water control (by using the two control valves). The materials look and feel like good quality. Tools are required to install, but the installation instructions are not detailed. This could be a problem for people who aren't handy with plumbing. When I installed, I had to make adjustments to fix toilet from not filling up. Long story short: make sure not to move the toilet internal parts when wrenching on the exterior supply hose. After eight months: no problems.
