Great, until it wasn't.
Ever since the next to last update the system takes a very long time to repsond to commands such as switching from Armed to Aboard. Support seemed to think it was my cell provider, but I have 5G Five bars at the slip and at home with T-Mobile. Also, this was not an issue prior to that update. A subsequent update made it a little better but not fixed (anywhere from 5 minutes to an hour to change status) as a result I am forced to leave in a disarmed state, rendering the system far less useful and not worth the subscription cost. I will wait until renewal time and if it's not better will be switching to another product. Shame. It was a great system till it wasn't.
