I just used it yesterday and I must say it is pretty cool and is simple to use. All you have to do is make sure your GPS is on. After my ride, I viewed my data. It showed Total Time, Total Distance traveled, Max Speed, Average Speed, and Max Lean Angle. You can view the graph that shows peaks and valleys or better yet, you can view your ride through Google Maps and it shows your complete route in red from start to finish. Pretty cool.
