Purchased this Washlet for my wife after she tore both rotator cuffs and personal care was severely limited. It fit our Toto one piece toilet well and was very easy to install. Note that you must have an electric receptacle nearby because an extension cord is not recommended. The seat housing and cover is a little larger than I expats but that is easy to get used to. This full-featured bidet seat odds controlled by a simple to use remote. It has easily identifiable controls for men and women with a variety of wash features such as water, seat and air-dry temperatures. It has eco settings to control temperature automatically based on usage patterns and time of day. I like the lighting for night use.  Also, it has great odor management with a fan system and air filter.  Clean the easy access filter monthly.
Enjoy!
