They got 'em now that detect laser too. And regardless of the on-off trick, I would have been woken up enough last month to avoid that in town school zone trap in slow traffic.

I don't know what they cost, but avoiding that 230 dollar fine could have gone a ways toward paying for the instrument, I imagine. Not to mention that there could be an effect on insurance costs now.

I've been saved from a speeding ticket by a radar detector once. It went off several minutes before I saw the Trooper.

I still got a ticket. Guy pulled me over specifically to check my window tint. Unbeknownest to me, it was too dark.
