Used the black box for 3 months but decided to cancel the policy as the ratings given by Bell were far lower than they should have been. Penalized for doing short trips. Penalized for going on a motorway. Penalized for picking up my son at 11pm. I have NEVER had a claim in 40 years of driving but Bell threatened to cancel the policy based on its rating for speed, smoothness, night driving. This would affect any future insurance be it car, house, anything. Having the black box was a truly awful experience. Keep getting “Your Policy is at risk of being cancelled as outlined in the 'Poor score' section in the terms and conditions.” It did not matter where or how I drove. DO NOT USE BELL INSURANCE.
