We have had the full-feature bidets from Japan and an Elite 3. The SlimEdge is our favorite, no question. The quality water connections and clean, thin, simple lines deserve a design award. The single control knob at a slight angle makes it comfortable and easy to use. Our neighbor came over during the 10 minutes it took to install the bidet and decided she had to have one. There is no reason to go to the trouble and expense of an electrical connection for a fan, heated seat, warm water, etc., etc.The SlimEdge does the job; no owner's manual needed.
