The P1 Pedals are very easy to set up and works very well with my Edge 810! I was really surprised by how simple it was. I was doubting the readings but did the same ride with my Vector 2 pedals and got the same readings. So it tells me I have some work to do to increase my power. What do not like are the cleats! It is crazy that we cannot use regular Look cleats for these pedals.
Took only a few minutes to install, insert batteries and connect to a Garmin Edge 1030. Works consistently. Provides great insight into how you pedal. Be sure to zero calibrate each time.
