I was disappointed that the original ROVSUN 5/20 PSI High Pressure Propane Regulator with Hose became unusable after only a few years. I ordered a new one and it works perfectly. We'll see just how long the new one lasts. I'm not hopeful, however I'm giving it a try. The last one failed when I was preparing a large dinner for guests and had no choice but to use another gas grill for a couple of items that are invariably better when cooked in a cast iron skillet which is why I bought the Rovsun in the first place. And by the way, what is a "horse" as used in the product description. Could proof reading be necessary?
