I'm one month in to my insurance policy with the box fitted, and it seems to be going okay. Well, in fact. Understandably, the box dislikes my occasional 130mile journeys home from uni, but I've never had a score lower than +8.26. I'm confused by how they work out the main score - I repeat, I've never had a score lower than +8.26, and yet my overall score is +8.10. When I called the company to query, I was brushed off. Would recommend for cautious drivers. The box is temperamental, and the stipulations for usage scores are long. Advertised as no curphew, but your score will go down if you travel between 11PM-5AM.
