Good quality, Good instructions, hot showers

At first I was confused on installation but once once I got the slope it was smooth sailing. I put this in a utility room on the first floor instead of the basement and I'm very pleased I did. Hot water arrives quickly and with good pressure. I wouldn't suggest using it to wash dishes and shower. It does have great pressure for showers. I really like high pressure showers.
