There is a reason it's priced the way it is. It's the best. The only thing that comes near is their own legendary
DSI that has existed for almost 8 years now.
The range at which it detects is insane: usually around 1,8km away, never less then 1km.
Also it's undetectable by the devices the police use to find radardetectors.
And if for any reason they are going to search your car: one click of a button and the radardetection part of the software is erased making it 100% legal.
Besides the radar detection it registers your km for business and private use of your car and compiles that into charts, extremely handy if you lease a car and use it in private as well. No more writing charts and carefully logging the miles yourself.
