So this heater was actually given to me by a relative, when staying over her house during the holidays. It was used in a fairly big basement, and managed to keep the whole room pretty toasty! It actually got to a temp, where I was questioning the season. I absolutely recommend this heater to those who don't have a heating system in their home, and really need a product that works, this will definitely be it! It isn't noisy, and does it's job. I would recommend being careful using this heater, as it can get very hot. Safety This heater gets hot. There's no way around saying that. It really reaches temps that are dangerous if you have small children or pets. I would recommend using this heater to heat a room prior to the room being used, instead of during. I think that would help if you want to prevent an accident. Also, it may be a fire hazzard, so I would recommend that no linens or any flammable objects be near the heater.
