I started off well with good score however when it comes upto getting rewarded my score would go down. So firstly dont expect any rewards. Secoundly just before my insurance is about to end carrot CANCELs my insurance claiming i was speeding with no evidence other than their black box saying so even though the black box is not accurate as i have checked by recording my own usage the the results being different. Thirdly bad customer service they email me that my insurance may get cancelled and when it does get cancel all they do is send a text message when i called they did not care and said it will get canceled no matter what i say
