I like how it has helped me keep my gasoline in check. No mess or spills as the gauge goes up when low, this helps keep track without having to go into the car. I dislike being unable to turn off the sound notifications so that the notifications will not pop every time I get up from my chair. Notify me if there is an issue with fuel flow or levels. It does exactly what I need it to do. There was a problem with our gasoline pump being out of service; this helps us avoid running out of gas before we get to the next station. The ability to monitor our fleet with ease! I love how easy it was for my employees to log in and view their vehicle's information at any time during business hours or even while they are away from work using an app called Workplace by Cisco (which we also use). It would be nice if there were more features available like being able to create alerts when certain levels reach critical points but overall very satisfied so far.
