Thankfully, friends installed your bidets in both of their bathrooms almost 2 years ago. I tried theirs while visiting and was amazed & have new meanings for the words clean & refreshing!  I bragged on, so much, a different friend bought one for me, and one or herself a several months back. Before the TP shortage. I installed it myself, a 72 year old woman, imagine that, (be sure to really tighten all nuts well), instructions were simple & straight forward. Works great!  I love it!  Excellent quality.  I wouldn't be without one now.  Use much less TP!  Wanted a bidet for years and am thrilled to finally have one!  Everyone should have one for good hygiene. Come on world!  Get with it!  Thanks Bio Bidet!
