Installation was a little rough since we had trouble getting it to slide back into place on our toilet. Added an outlet next to the toilet. After that it was smooth sailing. The buttons are self explanatory and everything seems to work as it should. I can't imaging using the bidet on anything other than full power, and the left and right buttons don't seem to move the water stream very far in either direction. The heated seat feature seems to be too much for the summer, but should be really nice this winter. Also the "front" button does not really direct the water stream very far forward, as you might expect; but it does cause the water to be "shot" in two different directions, i.e., straight up, and toward the back. It doesn't take long to get used to how the item works, and I do use this product about once a day on average. The bidet seems to be well constructed, and I would purchase it again, and recommend it to a friend.
