Based on 3 star review I was contacted in order to get a replacement valve and also promised a discount to help pay for professional installation by a Plummer. I did receive replacement valves but before arriving I packed the end of the valve with Plumbers putty and the leek stopped. Maybe my water pressure is too high? It has now been working well without a leak for over 4 months. Based on my experience I recommend a professional plumber to assist with the installation since I had to puzzle over this for a while before finalizing a satisfactory solution. It really looks and works great in a small wet room.
