We've had this product for about a year and it works as well as the 1st day after installation. The installation was really simple, water supply via a tandem "T", power plug-in and seat install. Couldn't be simpler. Depending on how convenient access is to the water connection and a power plug - you should not need more than just time and evolved patience to install.
The seat warmer is set to Mid Temp and so it the water pressure. The water cleaning option is so effective with an absolute feeling of 'clean' and actually being just that for both men or women, without a doubt.
