The most useful thing is that it gives us all kinds of information at one time, easy to understand too. Also can be used anywhere you need without any difficulties. I dislike how they charge money for the basic version and not everything is free or cheap in the other versions. If you are looking for an overall solution this could work well but if you just want some specific things like fuel usage etc then there might not be anything better out there. We have been able to see our whole vehicles operation more effectively as we get alerts regarding different aspects of them e.g. parking, tyre pressure, oil level, engine temperature etc. It also allows us to track their location which helps when scheduling maintenance visits.
