It has helped us monitor our tanks more frequently than we had previously done manually with a dipstick check or by taking note in a log book. The most important thing for me right now is ease of use/setup. It's not intuitive at all! I don't like when it takes several hours just to get something up & running properly. We have been able to eliminate manual logging which is one less task to do during busy times. In addition, it helps keep track of exactly how much fuel you are using each month so your mileage reports can be easily calculated.
