It was very easy to install. I was shocked. The only thing to bolt on was the quick release and the toilet seat slides right into place on it.

The fan also works pretty well. Removed smells really fast.

The light is not offensive to the eyes at night. And its easy to set. Just press it on at your desired time and it stays on for 8 hours snd shuts off.

The only con i have is that the seat itself is kinda big so it covers a bit of the toilet so you gotta be careful when doing number 2, its easy to get some on the seat.

Im highly satisfied with this seat
