my son has carrot insurance and it's been nothing but trouble. the box isn't as great as it sounds. if u live in an area where the roads are bumpy your score will never be great as it goes on smoothness as well as speed and usage. previous score of +10 were then changed by the next day, we have tried ringing them about some issues but their departments close at a stupid time so most people at work can't get hold of them. they do NOT reply to emails. my son was in an accident last week and so far the claim dept have yet to decide what to do. always over predict your mileage as top ups can be expensive. the phone calls have cost me over £10 contacting them in a couple of days. I as a mum thought it would be great keeping tabs on my son but I can not wait for this years insurance to be over so we can go with someone else who is cheaper.
