I've got a Road Angel after getting a couple too many points on my licence. IT's great for Gatso's etc, but i don't place too much faith in it's ability to pick up mobiles - i know this because a nicely painted van took a couple of pictures of my car 18 months ago and the road angel just sat there! They do also say though, that even if it does pick up the mobile cam, then the reality of it is the mobile cam has already seen you, so it's probably done it's bit anyway.
