Wife and I love this seat. Nice features, and it's so nice to feel clean after using the pot! Now when we go away from home we miss it (kind of funny thing to miss, but it's reality).
Easy to install for anyone that is a little handy. If not, let a plumber do it. Should be a minimum charge service call because it takes about 15 minutes. I am a plumber though so super easy for me. We did purchase a short extension cord to power it though since I didn't feel like adding an outlet close enough for the cord to reach.
We have had it for 2 years now and it works great.
