I have had this Optimus space heater for a few years now, and it has never failed to do its job when I need it! My favorite feature is the remote control, which I definitely recommend when buying a space heater. It saves me from having to get up and physically walk to the space heater to change its temperature. It has many other great features, including the oscillating fan, which can provide constant temperature for the whole room. I also love the temperature thermostat option, which constantly senses the temperature in the room and then it adjusts it to your settings. It also has a "high" or "low" heat option, which lets you control how much heat output there is within a room! Overall, this space heater has definitely kept me warm throughout the winter, and whenever I need to use it!
