I’ve had compustar in my trackhawk for over a year, among many other security modalities. I was hesitant because I didn’t want to change my routine of in/out of car. I had guardian for the first few months. I agree it’s useless. And I was always paranoid about bad players on there. No complaints with compustar, worth every penny. Functionality is well thought out — proximity unlock, timed lock, and the app’s design. They offer dash cams (front, rear, interior) as well. I have the front and rear. All controlled by same app of course. The geofencing and related alerts are very accurate. Definitely helps me sleep better. A side bonus for iPhone users, when have do not disturb turned on, you can still allow certain apps to alert as usual (in the settings of do not disturb) so the alerts can still come through in real time.
