I find the operation and options excellent: full pressure is too much for me but it's simply adjusted by arrows, and heat choices are cold, warm and hot. One automatic posterior clean cycle button and stop button are on the seat. Or choose, stop, or change the functions instantly with the remote control -- you can place it where you prefer. I consider the little tones quiet and reassuring that it's working. The seat sensor activates a little water dribble at first, I suppose to keep the functions clean. Automatic UV cleaning activates when there's no more weight on the seat. Compared to many other bidets this seat's low profile and streamlined lid look especially sleek. I installed mine without much difficulty (after watching Web videos), I only wish the cord was longer--barely 4' but I got it to reach the outlet on the opposite side by running it behind the tank. I installed a replacement skirted toilet [its connection to the water intake is tricky to reach, however] at the same time so did not have to remove a prior toilet seat. Therefore the top mounting bolts worked easily; but there's a very slight give to my seat's placement likely because I don't have a man's strength with a screw driver. No complaints, really, and plenty of raves from me!

Easy to use, low profile, works well. Only 2 things that would make this a 5-star product - disable the little bit of water rinse that happens anytime the seat sensor activates and instead only activate it before starting a wash cycle. very often, a bathroom visit doesn't require the bidet to be used to the water dribble is wasteful and annoying to hear the moment the sensor is activated. - add light sensing to the nightlight so it doesn't have to be manually turned on and off.
