Received this as a Christmas gift Dec. 2018. Used once, then went to use a second time a month later the control panel would not work. Contacted Mastercraft and they sent a new panel. Used only four more times over the past year. Went to use again tonight and heater was pegged at 300. Will not hold temp at all. I contacted support on line as call center closed. I keep the unit under my shed roof so out of any rain and snow. Many posts online regarding bad panels. Cripes, find a better panel Mastercraft.
