The device is excellent, does it works exactly how the information says. However, in my country, police uses laser speed detectors so you have almost no time to react after you are scanned by police. That means if you drive 25% or 30% over the speed limit then you may probably not have enough time to reduce the speed and you will probably be caught by the police. The system should have a retardant intervention system. On the other hand, there are no instructions about how to turn on/of the laser detection function, so basically you don't know whether it's working or not until you are pointed by a cop in the highway.

this is a real good radar for the price, the only thing is that, it gets annoying. the "x" band goes off every other second. but that's what its meant to do. so overall i would buy it again
