This faucet is absolutely beautiful and worth the money.  It adds such an elegance to my bathroom and my sink.  I love the way the water flows out.   On initial set up, it did flow slowly, as other people have said in their reviews.  We removed the regulator and it works perfectly.  I love to watch the water flow into the sink and I love the sound it makes.  It's like going to a spa.  
To keep it clean, after I wash my hands, I just rub it down with my hand towel.  It does show water marks, but I just consider that a sign of a lived in home.  Nothing can be perfect all the time, but this faucet is close!
