My wife bought three electric fan heaters. Ominously, they took a long time to arrive, missing Christmas. They are pretty basic. In theory, switching on the 'temperature switch' starts the heater. But, under the heaters is a button, called the "interrupt power after dumping", which needs to be pressed to get the fan to work, But there is no means of keeping it switched on. This is a basic design error. The instruction booklet is useless and full of dictionary English.It is a waste of money. If I had been permitted, I would have rated the product '0' = unfit for purpose.
