Good overall service but 'usage' is a joke. I get different scores each day, even if at the same time of day as the previous day before and the same journey time and it seems to constantly bring my score down. It says usage is for the time of day but it's not very consistent when it rates on this. Also, if you drive in rush hour or peak times the score goes down most of the time, no matter how well you drive, which is a con, as I have to drive during those times most days. Would be better if 'usgae' was more consistent. That being said, it was quick to set up, and I like being able to keep track of driving scores etc. Excited for money back reward.
