I bought this two years ago for my bedroom and I was shocked how well it worked. When I bought it, it was during winter in Northern Wisconsin and the wind chill was -46. This heater worked very well. No smell to it like most heaters. I still have it and it works like it is brand new. Performance Plug it in, turn it on, starts up pretty fast and heats up the room very quickly. Ease of Use Very easy to adjust with the thermostat. Set it to how warm or hot you want it to be or to shut it off. Durability Have had it for two years. Design Pretty basic design for a small heater. Safety I have knocked it over and within less than 30 seconds, it turns itself off to prevent overheating. Recommended to be place on a desk or table. Keep away from curtains.
