It's a really good detector indeed. However, not everyone likes the safe list. Also there is still no laser detector add-on which was promised years ago.
However, it's still fully undetectable for any radar detector-detector that the police uses. In Holland you're only allowed to use this detector with the GPS based warning. The real radar detector software is not allowed to be installed and used.
Therefor all Dutch detectors only warn for GPS based speed traps. The only thing you have to do is download the UK software from the internet to have full detector service
If the police would ever stop you to see if this is installed, with 1 push of the button you remove the software/erase the memory. So no tracks that you were using it illegally
For +- 450 euro you can get the Beltronics 975 whiich has about the same detection range, but requires some modifications to make it undetectable for the police....
