Review on Coros Performance Optimization Efficiency Strength by Robert Castro

Running with a power meter is like replacing a clamshell phone with a smartphone! Power is much more reliable than heart rate as it provides instant feedback on your performance. Coros POD provides 3D analysis so you know exactly where your power is distributed: horizontally, vertically or across. I love that the device is small and light so you won't notice it when it's on your belt, but it's durable and stays closed even on the trails. The performance you can get from it is beyond what I've seen from the competition.
