The ease of use, the fact that it is so simple to install in your vehicle and even easier to manage from our office or mobile devices. It also makes for an excellent customer service tool if you have any issues during installation or operation. I would like to see more features added as well as make improvements to the overall system itself. We are using this software to track all vehicles within our fleet. This allows us to better monitor fuel usage and ensure we're not wasting too much money at one time by having multiple drivers operating out of their own personal car.
