The main selling point of this device is it's battery life. I have logged in about 10 days of use since receiving it with a total of 23 hours of usage and it's still at 40% (I charged it to 80%). A normal three hour ride will only consume about 7% battery.
My only gripe with the device is that rerouting is unreliable. It has a hard time finding the nearest alternative route when you deviate from the course. You could be approaching the next point and the device still wouldn't recognize it until you've returned to the course. I hope this improved with software updates in the future.
