Review on 🔥 Fast Heating Portable Space Heater: 500W/900W Ceramic Personal Heater Fan for Office Desk Room - Tip-Over & Overheat Protection Included by Michael Foster

This is a very small room but it works very efficiently. I don't think it can heat up a huge room, but a small bedroom of about 400 square meters can be cozy in minutes. It has two settings that help control the intensity. There is a setting on the bottom of the heater that allows the heater to only function when placed on a hard surface. If you put it on rugs or an ottoman, the heater won't turn on. This is a fire/damage prevention method and can be used around pets or children. If the heater is knocked down from the side, it turns off.
