In the USA it seems to work great...
i love the data and the video capture using my iphone 4s on a tom tom mount.
relatively speking from run to run in a days track time you can pin point your speed, braking and speed in the corners .. i love it
its the best bang for the buck for us weekend warriors for sure
i recommend it..
