I bought one of these from Walmart, about 3 weeks ago. Other than being really big, it keeps me nice and warm. I would get another, in a heart beat and will never go back to any other style of portable heater.
Bought two of these (not refurbished) this morning at Menards for $49 each. They had tons so if you have a Menards near you check them out. They aren’t selling this item online, you have to go to the store.
