from getting my box fitted almost all of my scores were between 9-10 in total so when it was time for my reward to come through, a lot of these scores for usage dropped dramatically without making any changes to my driving patterns, and since the first reward came through this has been more of the same, I've have had to complain about scores numerous times and always get the same response that its been sent to it and someone will be one the phone within the next few days to come and look at the black box, as there have been numerous times that it will still record the car as being driven even when i'm at work and the car is parked with the ignition off. upon speaking with someone from carrot about one of my recent speed scores he had pointed out that a speed of 26mph was recorded in a 20mph zone but this should not of caused my speed score to be -9. if there is any more persistent faults I would like to be followed up with the phone call that is being promised and eventually have someone come and check my box. other than it taking 30-40 minutes to speak to carrot on the phone the reward system works really well and I like being able to check my scores all the time. the feature in the app that shows where your car is parked also is very helpful
