I wouldn't trust this with my life. I'd rather the government chop off a finger than have me install this. Company uses call centers over seas. They read off a paper for troubleshooting. The device randomly dies making you tow you vehicle to the nearest service center. They don't pay for any of that. What they do is charge you 75 dollars for each malfunction that's happens. They reuse all there devices. so you could be getting someone else's device that they threw around and didn't take care of. Iv seen how they run things. They are penny pinchers. I bet the CEO Kimberly has more than three houses and a Tesla. Let's just say if we made these corporate big wigs install one in there vehicles they would end up failing the test or flake out on the six months because the device stop working randomly. I'm not the best human because I got caught drinking and driving but I know when somthing is inhuman. This device can ruin people's life's. Causing them to go homelessness. I begg that the people who run this company to update you technology. Don't be stingy.
