Radfan Radiator Fan - Classic Standard 5 "Couldn't believe how good it is" Miss Rollinson 27 November 2019 I read the reviews and remained sceptical. But the product is amazing! It does exactly what it says on the box. The room is always cold even when we put the radiator on. With Radfan it soon warmed the whole room. You could tell the difference as soon as you left the room. I would highly recommend it to anyone. There is a sound from the Radfan but it is not very loud but you can hear the fan going. The sound does fade into the background as the TV covers it. I will definitely be buying more for other rooms in the house.
