Cobra here, used, from Ebay.
Paid for itself already. Odd thing happened the other day though. I was braking for an onramp when I got a laser alert. Normally, this means that if one is in violation, one is about to be violated - the alert comes too late to be any good. But I was braking for a sharp bend and going much slower than the limit, plus there was mild traffic too. I wonder what possessed whoever was lurking around to have a look at me -- the car or curiosity or boredom? No lights, no ticket in mail, no nothing. Go figure.
