The ease of use, reliability in field applications as well as being able to monitor our vehicles throughout multiple states/countries worldwide is what we love about this product! There are some minor issues such as not having an option for "manual" entry instead it's always automatic but I think they're working towards fixing these problems soon so no worries there yet.
Overall great system!! We have been using FUELFORCE since 2008 when their first version came out - now upgraded versions keep coming along every few years which has made life easier than ever before!
