A year later it is still working perfectly! It gets frequent use and we have had no problems with it. We had it installed professionally when we had new countertops & sink put it, so I can't comment on that aspect. It's a little loud, and makes a sort of metallic sound when it turns on, but I think that's normal. I run it at night after the baby has gone to bed and it's never woken her up, so quiet enough I guess :)
