No. They suck. They're parasites. They're not even very good at that. They're really more battery police than making sure people don't drive drunk. They also forgot that the people with their device are the paying customers. If you are bad to those that pay your bills, they're going to stop paying you.

Yes they do suck and Sean K. Is very right I hope intoxalock get what they deserve taking people's money because if the battery dying and violate you because of it and it goes against you in court!

I agree with all 3 of you. I returned the device after my time was up and they keep charging me. Try calling them every day for weeks and listen to them typing saying that there system is down. Complete BS

They've made $100.00 off me THREE times so far for failing me after passed blows. I'm trashed according to this device then so er all within seconds but it's not faulty. Then what do you call it cause its BS
