My wife and I used the fancy toilets in Japan and always wanted to own one in our home. Due to the toilet paper shortage, we began our research and found Bio-Bidet. We purchased the Slim One Bidet and have never looked back. A few guests who have visited us and have used the toilet left our bathroom only to let us know: "well, that was an experience,"  We have recommended Bio-Bidet to just about everyone we have talked with or visited us. Fairly easy install and use. Love it!
