I had mine above the mirror on the drivers side, you couldn't see it thru the stock sunshade (whatever the tint visor is called) even when the leds flashed, forward I could pick up radar/laser for a ways and rear I never noticed a time when it didn't work, well atleast if I went by a parked cop running radar it would go off as I drove away. but sadly, I lost my window clip, well my wife misplaced it. btw, I didn't have it hard wired but it would be nicer having a direct wired to the dome light power for a clean finish
