Power meters are by no means perfect devices. A robust design with simple functionality has yet to be created in my opinion (although they are getting better); and they are expensive to boot. A power meter requires a level of technical and analytical aptitude that not every athlete will possess. However, if used to correctly, a power meter is a powerful tool that can increase training accuracy and facilitate a much higher level of post race or work out analysis. Utilizing a power meter within a multisport pacing strategy can give a tactical edge as well.
