Query: Questionable at best.

I bought the unit to replace a 40 dollar Cobra unit that failed after a year. Tested the unit with a 2000 mile road trip right off the bat, and have been using it in the city for the last month.1. The range is poor, I would say no more than 1000 yards when set on highway, even less when set to auto detect. At any rate it doesn't inspire confidence as it generally doesn't pick up a speed trap until maybe a second before it is in view.2. The window mount is ok, not great, and the power cord is short and coiled, very overt.Overall I regret buying it, poor performer compared to my old Cobra and cost 3x as much. I would have been better of buying a new 40 dollar unit every year.
