Setting up the insurance was straight forward. Fitting of box was carried out quickly and on time. Scores generally are quite accurate, although on one occasion I have had a 6 hour journey recorded when it should have been about 26 mins. Emailed Carrot to query this and have had no response :-( I agree with other users that too many short journeys do affect your scores. Apparently 7 short journeys within a 24 hour period affects your score. Wasn't told this when setting up my insurance. For example stopping off for petrol near home and turning off the engine will count as one short journey!! ??? I haven't yet received a card for the rewards, but am hoping that I will get one when my 1st reward period is due. It seems a bit hit and miss with other customers.
