good price and does what is says. NEEDS BETTER INSTRUCTIONS. they just tell you you can change things in the settings. that's it, no instruction on how or what you are doing. I think I accidently set a timer. every night I go up to my shed the heater is running but the fuel is almost as full as I left it the night before indicating it hasn't been running long. very frustrating. now I just unplug it when not in use
