Bought the Stages Power meter for my road bike that has a Shimano 105 drive train. Installation was easy. The unit paired easily with a Garmin Edge 510 and a Wahoo Elemnt Bolt. Cadence is spot on. Power matches my Kinetic trainer, so as far as I am concerned, power is accurate. Some may have a problem with a single leg power meter, but it is all I need. Great value. Many power meters are 2x to 5x more expensive. For what I wanted, the Stages unit is perfect.
