While having a telematics black box on the car, the data they give you on your portal regarding your driving score compared to what actual driving you're doing is bs and does not make sense most of the time. Driving at 55-56mph in a 50 limit gave me a score of 24% while driving quite a bit more than 70 in a 70 limit gave me a score of 40%. Their customer service operators don't have a clue to why this happens. So unless you are really really tight on money, don't buy a policy where you yourself! have to install the black box. It's not difficult to do that but I would not recommend a black box car insurance policy.
