As a now former service-center for Intoxalock, I can absolutely say that they have many issues. First and foremost, their hardware WILL drain your battery. They claim it is only an issue with clients that do not drive their very often, or it is an issue with an old wornout battery. I had too many clients with new batteries on their everyday driver to believe any of that. I had a client buy a brandnew battery and install it into their vehicle that was dead in my parking lot. The new battery was dead inside of 48 hours. Also, their 'customer service' is anything but that. As a service center I would expect to not have to wait on hold for over 30 minutes when I call with a problem. But that is exactly what we dealt with.
