Excellent product: works perfectly, easy to update, hangs satellites quickly (less than one minute). The reporting of hazards zones is optimal; only a fixed radar reported did not exist (to do with the Update base ...).
In short, I recommend to all those who are tired of being flashed for thoughtlessness and some Km / h above the limit.
The system reminds you to order at the right time and you avoid unpleasant surprises ...
