Installed brushed nickel, model UP7009.  Easy install.  Bought it for the handsfree feature and it was discounted through Costco at the time.  Works great and nice to have the flow and temperature adjusted when it comes on.  
Side Note: Had issue with hot water flow being slow.  After some checking, the issue was piece of the rubber gasket center was not completely stamped out.  Removed and had the flow.
