We bought this a few weeks ago and so far so good.  This was an upgrade from a generic sprayer nozzle that sprung a leak and flooded down through the ceiling below.  Install was easy and only took about 15 minutes.  The bidet seat works great and the remote control is nice because it is mounted where it is easy to read and reach.  We have tried every feature and it works great.  The seat seems to be very good quality and we are hoping it last for years to come.  I gave it 4 stars because the water reservoir seems too small and it runs out of warm water very quickly.  The Bidet functions have a 1 minute timeout and the online FAQ says the warm water lasts 50 seconds which seems about right.  It baffles me that they didn't size the tank to last the entire 1 minute of operation.  The 10 seconds of cold water at the end is slightly annoying.  Other than that it is a good seat for a good price.
