It typically detects from about 0.3-0.4 miles away, which is plenty of time to slow down

I have plenty of time to slow and often I don't even see the cop for 1+ minutes after an alert

Or so before I finally see where it's coming from which leaves me plenty of time to slow down before the problem occurs... solid product at this price point!

Provided you are driving fairly sensibly (not more than 20-25mph over the limit), this unit should give you plenty of warning to slow down in time to avoid getting a ticket, provided you aren’t tagged out in the open by a hidden cop with instant-on POP radar with no other cars around (in which case, your $300-$600 Escorts, Unidens, and Valentines will most likely give you the same too-late warning).
