Purchased for €15 on 15/10/2018, the overall impression is that it is okay, neither bad nor good. In the positive aspects, it heats up within seconds and is good for a small room. It is a simple device that consumes energy and produces heat. Apart from two settings and protection against falls, it doesn't have anything else. In the negative aspects, it doesn't have a thermostat, which means it is not suitable for "permanent" heating. It is meant to be turned on for a short while to warm up and then turned off. If left on, it will work regardless of the room temperature. Also, like ALL electric heaters, the more it burns, the more it heats up. Claims of energy efficiency are big lies. Air conditioners and heat pumps are more economical as they have a higher efficiency rating. All other devices such as fan heaters, stoves, electric radiators, etc., give back what they consume. Generally, for greater flexibility, it is better to have multiple settings, at least two like this one, and a thermostat. If you only need it for a short while like me, the thermostat is not necessary. The photo is wrong, it is from a different model. It only has the rotating switch with the settings, it doesn't have the on/off switch shown in the photo nor the other end on the right.
