In the past 20 years, I have had three premier bidets  in my house.  They have operated flawlessly.  When redoing a bathroom, I intended to buy the same brand, but then saw an ad for Biobidet and was impressed by the thousands of reviews.  Yet, still skeptical, times being what they are, I read more articles on the technology.  Biobidet's design addressed a lot of concerns and then some.  I I was also motivated by the fact the Biobidet is a US company, which I seek to support --all things being equal.  I decided to chance it (also has an excellent warranty).  I have only had it for a month, but it is outstanding. The fact that the nozzle is stainless steel puts it in a class by itself. But there are so many things to applaud: the wide cleaning, the water stream propulsion, the comfort––all of it is top of the line.    Hats off to Biobidet!
