I have a Road Angel with the additional Laser Detector fitted.
The Road Angel is good for picking up Static and Average Speed Cameras , Accident Blackspots etc etc.
But i think the Laser Detector for picking up Mobile Speed Cameras is a bit of a gimmick as it only goes off when the Mobile Camera has the laser is on ya and then i think then its too late to react "You've been caught". :dapprove:
I only tend to use mine for Static Cameras when i'm away on Roadtrips in unfamiliar places where the cameras can be hidden
And for the GPS speed function.
