Real rating -zero stars. AVOID Sent black box-plugged it in as I’m confident I drive well. Average rating not explained. Then a letter giving me a weeks notice they are cancelling the policy as I have broken the rules I’m unplugging the device.i once notice it had fallen out when giving a work pal a lift home -I think he stood on the wire. Anyway,the say by unplugging it I have breached the terms and they are cancelling-with short notice a major hassle.no warnings cancelled. I’ve been on the road for about 18 years. Never claimed a penny from an insurance company1a total Scandal.
