Do not use this!
I paid for the device and connected it. Initially, it recorded my driving activity and presumably transmitted it to DIMO. The rewards were accumulating but I had not convert any to cash. I then received notification that I would be charged for using the device. The prospect of rewards (and all accumulated rewards) have disappeared. I was charged for a service that I did not need and would never have paid for. The money paid for the device on the basis that it would be used to gain payments is totally useless. A complete and total waste of money.
