We bought this Slim One less than two years ago, and it started to have less pressure shortly after the one year warranty ended. The water pressure changed every time I unplugged and plugged the unit. And about two months ago, the nozzle part started to leak, the leaking started from 30 minutes and now it won't stop after 3 hours. I was informed the repair cost is as high as purchasing a brand new unit. I have another toilet seat that I used for 8 years from another brand and didn't have any issue so far. I won't purchase this brand again.
