If you are lucky, it will catch a stray laser shot at another car, but this is rare. Instead, it just lets you know you are laser fucked.

I have had mine for almost a month (since I live in Cincinnati, I went to their headquarters personally to pick it up) and love how it picks up every garage door opener, burgler alarm, automatic door sensor, and so on that I pass by.

For every one-thousand false alarms, it actually picks up one or two real ones though. Overall, I think this product is overly hyped.
