For years I ran another companies remote start/security products. I decided after some issues to give compustar a try and have not looked back since. They work and work as they are designed to do. I have the Compustar unit with alarm add on module in my silverado. Upgraded the remote kit to the 2 way T12 3mile remote w/ Drone mobile bundle. I can do it all right from my phone. Next up I am going to install the RPS Touch to the unit so in the event I don't have my keys or phone on me I can still unlock and gain access to the car.
