Anyone ever heard of it or used it? It seems like a very effective way to deter theft, and according to its track record, no car has ever been stolen with a properly installed device. Its the only anti-theft device you can get an insurance discount with in Mexico where cars are stolen a ton, because it stumped professional car thiefs (official test). Not too expensive either. I was thinking about putting one on my G2 along with a cheap alarm. Thoughts?
