Hansgrohe PBV with Diverter 04447000 Ecostat Pressure Balance Trim S best

Product Name: Hansgrohe PBV with Diverter 04447000 Ecostat Pressure Balance Trim S best
I am selling this Ecostat Pressure Balance Trim S with Diverter in the chrome finish (item number 04447000). It is for use with iBox Universal Plus (item number 01850181), which is not included. It is suitable for a two-function installation, such as a showerhead and tub spout or a showerhead and handshower. Do best not use it in a one-function installation, and do not use it with a diverter tub spout. The box has been opened, but I never installed it. According to the parts list in the booklet, all the parts are included. The finish has a few faint, minor scratches. The manufacturer's retail price is $427.
