From the very beginning, I’ve had nothing but problems. The reason they’re so good on trust plot is because they’ll call you back and offer your money back but that does not help all the time and the marks against you you can never get through to customer service you turn off your vehicle get out of the vehicle and it goes off without you being in there they charge you $200 extra to re-calibrate it it happens all the time in the end. I am one month out and they just keep on hit me with tons and tons of charges. They said they were not. They are corrupt do not use them.
