Love this product. I've had my seat for over 2 years. Installed in 15minutes and unit works flawlessly. Doesn't look bad either for an after market. The mobile wall mounted control unit is simple to operate and the original batteries are still working. It has all the controls you need: water pressure, water temp, air dry with adjustable temp, seat temperature, wide or narrow water stream and movement control. Couldn't ask for anything more.
