Excellent bidet.  Worth the extra money for the warming seat and heated water.  Really does make your time spent on the throne infinitely more pleasant and hygienic.  Easy to install as long as you have a/c behind the bowl.  Also make sure the splitter fitting fits the diameter of your hose. I almost gave up until I realized that there were two possible ways to split the intake hose...1) by the valve in the wall and 2) by the tank of the toilet. You can install the splitter in either place and one of those two is bound to be the rig he diameter.  Excellent shipping and communication from Mayfair.
