They charge you random bogus fees daily. You get this handleheld sleeve that they charge you like 9.99 monthly for and youll probably never use it. Customer service reps are all from india so its likely your being scammed and theyll prob steal your info while your on the phone seeing as people from india are common for scamming. The only time i was able to speak to an English speaking person was when i took the equipment off the car and when i had it installed. Twice. Thats shocking. The Indian people always blame all the issues on your car battery because they have no idea what the device actually does or how it works. Its very expensive. You have to get it calibrated every couple months but thats pretty normal. As long as you drive your car every other day and keep the battery charged you shouldnt have any problems. However this thing drains your battery even when the car isnt running and it really drains the battery. Its very easy to use but i dont trust the customer service reps at all with my information. Dont give them anything you dont have to. If they ask you for your social thats an issue. And its happened.
