Conclusion: NO I WOULD NOT RECOMMEND THIS TO ANYBODY! Any time I've passed a cop it hasn't gone off. I don't know if it's because they're not pointing the radar gun at me or because the thing doesn't work. And, what's even worse is the false alarms i get! When I'm accelerating hard, the Lidar detector will go off. Every time i push the gas pedal hard it goes off. I don't understand why. But it scares the crap out of me. In the manual it says "Lidar" is a laser from a cops radar gun.
Conclusion: This was OK when I first got it. sometimes it would randomly go off because of interference but every time there was a cop there it picked it up way before i saw the cop. Now 6 months later it is randomly going off like every 5 min for no reason i would not recommend this product to ANYONE!
