They give you a little orange box to attach to your windscreen, and tell you to use the app, always have the application running on your phone with the Bluetooth connected to the orange box. But then, when you do get the app it works for all of 3 weeks, never to load again. Every time I go on the app it crashes, they then have the cheek to send you a letter saying they're cancelling you policy in 21 days if you don't start using the app, which you try to do. I tried to ring them on numerous occasions but I was on hold 30+ minutes at a time and never got through. (I work 65 hours a week and haven't got time to waste listen to elevator music on repeat) They are now cancelling my policy because I never started using the app that doesn't work, with 7 day notice to find a new insurance policy.
