Query: Disappointing

I ordered this as a replacement for the more expensive model which was out of stock. I should have waited for the more expensive model. I installed the cheapo model WV2 yesterday and.. One valve can only be turned with pliers and the other valve turns easily, but the flow of water is unchanged. The arm is too short. It is impossible for me to get the mirror in the right position. As advertised, the mirror does not fog but you waste too much water in the process. I called the showerTec 800 number for help this morning, but alas no returned my call.
