Review: Fantastic bit of kit - This is really effective. It has a very strong magnet, but it is easy to remove. I wouldn't recommend it if you are precious about your paintwork. The cable is very long so you can reach anywhere on your roof. There are several different modes, controlled from the adaptor. Fantastic value for money. I feel much safer now I have it
