Received both of mine three weeks ago. So far I have installed one and everything works great. The install was easy, everything fit tightly (didn’t even have to use the plumber’s tape, no leaks) and it was working within 20 minutes of starting the project. This is my first bidet but I had it down and figured out like I’ve been using one my whole life within a couple days. I can't find any use for the glow button, that's the only reason it's not 5 stars. Can’t believe I’ve gotten this far in life without one!
