Decent insurance company, I do feel that some of the acceleration scores I am getting are a bit over exaggerated since it's only a 1.6 but I get it they want you to adjust your driving to suit how they want it. However since having my black box installed on the 1st of March I've covered a recorded 736 miles and have an overall score of 94 even though my acceleration score is all over the place, after two months I saw my premium go down for my driving score which I am very pleased with, my only real complaint is how long it takes the telematics to update but we can't have everything. Customer support has always resolved my queries, questions and the one claim I made for a stone chip in my windscreen was hassle free despite being called "mate" by the chap filing my claim, for the one claim I made on my windscreen I used their preferred repair service national windscreens who were very good and did the job well even sent me a message with an ETA. So long review short providing you play by the rules and drive how you should be, you will be rewarded. However if you have anything with more than two cylinders, or unless you make slow progress, then your acceleration score will go down quite a bit.
