My Coleman propane camping stove has been used only 2 times. The first time, the proane bottle and regulator froze half way through cooking a meal. Coleman replaced the regulator and it did no good, the lines still froze. This year the left burner quit while we were in the wilderness moose hunting requiring us to cook our entire meals on one burner. I threw it away when we got back to town. Don't rely on this device.
