Lots of posts on this around. From what I've seen, most people who have this are disappointed in the operation and wish they hadn't paid for it.
There are aftermarket kits around that apparently work much better (and that use your original remotes) and are cheaper to boot. I have the Fortin in our car and am very happy with it. Just press the lock button 3 times to start (or configure to lock-unlock-lock).
I've used the Compustar with the Drone Mobile module in my last couple of cars. It works great. I can ask Google home or Alexa to start my car. Also has a phone app. I bought my car 2 weeks ago. Best Buy has them on sale for $299 on occasion. It does have a minimal subscription cost to use the smart features. My last car was a Hyundai. I used the app to start the car but it would take minutes to start the car. The Compustar was instantaneous.
