This drinking water faucet matches my Kohler Avi kitchen sink faucet perfectly, and it seems to be very high quality. It installed easily on a stainless sink. If an external RO is not being used for it, the red and black hoses are not needed; only the 3/8" supply hose (with a compression fitting) is then needed. Most of these faucets sell for much more than from this eBay vendor, making this a very good deal.
