AVOID THIS COMPANY ALL COST!! They set you up to fail … I have 2 vehicles. I used LifeSafer on the one, and Intoxalock on the other. I have NEVER had one problem with LifeSafer. On the other hand, I have NEVER had anything but nightmares & headaches with Intoxalock. Listen, I got a DUI. It was an act of selfishness and carelessness on my part. I deserve the punishment I got, and I take FULL RESPONSIBILITY for my actions. And honestly, I think the ‘interlock device’ concept is great in every way. That said, Intoxalock is a complete scam. It would be impossible for me to cite all the examples from my personal experience. It would require volumes. All I’ll say is this: AVOID this fraudulent company; Warn others to avoid this fraudulent company; and then, contact the Attorney General in your state and begin seeking legal remedies where this fraudulent company is concerned. There are countless lawsuits against this fraudulent company. See about joining one of those … It is now my life’s mission to expose Intoxalock, so that they are no longer able to wreak havoc on people’s lives.
