It seems to do what it is supposed to do. So far we've only used it for a week or two. It was extremely difficult for our plumber to connect this to a non-InSinkerator hot water dispenser fixture. It required phone-ordering a separate special part from a 3rd party vendor (the snap-connect fitting), and then multiple other types of connecting pieces that our plumber had to make multiple trips to the hardware store for. When we ordered it we weren't aware that it was only recommended to be used with InSinkerator fixtures, but we probably still would have tried to use our own preferred fixture, to match the style of our kitchen, and not expecting that it would be SO difficult for our plumber to make the connection. It seems like a unit like this should be designed so that it could be used with any type of hardware, considering that most customers would probably want to have their choice of hardware to match their other kitchen fixtures.
