It’s better than the Viper I had on my last truck…

Differences in how the software handles the handheld remote and the Drone Mobile phone remote-start are annoying; the Drone Mobile/phone app seems to lag in updating status. The ""uptime"" touted by Firstech are meaningless when one needs the phone functionality and it doesn't work. Tech sup[port sometimes responds and don't offer much in the way of support. There are many options available and the installer may not discuss those with a customer before installation, so one needs to do his own research prior to installation.
