Terrible company do not pick this company to work with if you do plan on lock outs for no reason for instance, I hit a pothole, and it triggered the machine to give me a lock out, I tried to find it, but there was no way around it the company made me pay for that when it wasn’t my fault. so much more I could write about this company. I’m just trying to warn you look at other options. Not one lockout did I get for alcohol? It was always malfunction with the machine. It took all the battery out of my vehicle so that would give it a lockout, terrible company, save your money and pick someone else to work with. Please believe me.
