I did something pretty dumb in our humble opinion. I went plus I was trying to save currency plus bought this ultra cheap portable space heater, then this ultra cheap portable space gas furnace was the absolute worst! I have experienced what space heating systems are supposed to be like, plus this was not even close! First off the thing was cheaply made, then just picking the portable space gas furnace up made me upset of either burning myself or the space gas furnace falling apart, however and then on top of that, the portable space gas furnace hardly heated anything at all. It provided some heating within 3 feet of it, but that was it. I have experienced portable space heating systems that will heat an entire room plus they are no bigger than a blender in your dining room! This is what I get for trying to go mega cheap. I should have known something wasn’t right when I was able to buy a portable space gas furnace for 15 dollars plus some change! Portable space heating systems are usually 50 dollars if they are on sale, plus correct price you are looking at around 73 or 78 bucks. 15 dollars was nothing but a tip off that this was not a quality portable space gas furnace plus most likely a piece of junk. And a piece of junk is exactly what it was, however so if you ever see portable space heating systems or portable s for pennies, do not buy it! It is going to be a major joke just love this portable space gas furnace I was dumb enough to buy.
