Overall, the product works well. Both hot and cold dispense well and easily. I'm not thrilled with the faucet because the goose-neck is low and only shallowly extends over the sink so it doesn't leave a lot of clearance. Also, I understood from the sales information that the cold lever would remain on, but it doesn't; you have to hold it.
This was a replacement installation, so the area under the sink was full of plumbing. Still, I expected an easier time. The 3 tubes that run to the hot tank are not long enough to easily arrange things. And the general instructions do not assume the addition of the filter unit, nor do they account for the extra spacing needed. It took me double time and some ingenuity, but everything got installed and it works. 
My biggest complaint against insinketator is that the better and nicer styles of faucets are not only not standard, but they cost almost as much as the standard unit.
