I bought this and had a plumber install it. I did not have him hook up the filtered water, which I wanted to. It took up way too much space and to change the filter we would have to unhook everything to do that! No way! After only a few months of use the faucet drips after you sit it off and water comes out of the black switch on the faucet that you press for spray or regular. Have not called the company yet, not sure how customer service is. Wanted to love this, looks so good. But way too expensive for this to be happening!
