The ability of being able to capture all aspects of driver behavior in one place is amazing! I am not sure how much time can be saved but this has cut down our work force drastically by providing us with an accurate way for reporting purposes that we could trust. It was easy enough setup as well - there were some initial hurdles getting up to speed once you have been working elsewhere without using TM previously. We are looking at ways around those issues now though so maybe they will become less common over time if people realize what their benefits truly look like (and aren't just fluff). In my experience, we've used TMs app mainly during out-of-office hours when someone else isn't present who would normally use them. This helps ensure accuracy/reliability because only drivers themselves know exactly where they should or shouldn't slow down etc..
