I love that coolix comes with everything you need to get started right out-of-the box, no separate mounting or power supply needed! You can set it up quickly as well as use your phone via bluetooth connection (also included) - perfect if there are other people in charge who might not have experience setting this stuff up themselves. The app does require some technical know how but once figured things seem fairly intuitive. If someone has never used something like this before then they will probably be amazed at all their capabilities! We were having issues getting our clients' data stored properly between sessions so we could send them more information without needing access again when returning next month/year etcetera. This solved those problems beautifully by allowing us remote control from wherever was convenient & sending secure messages too while doing what seemed impossible just 5 years ago!!
