Nice quality and made in the USA !. I hooked this unit up a little differently. I connected it directly to the refrigerator. I was not anxious to drill a hole in my sink at this time. Sometime maybe in the future, I will install the seperate faucet .After about a week, the water was clear and tastes great. I need the purest water I can get due to health concerns. Reverse osmossis was out of the question due to wasting much water in the process.
