I used inride for a season and I thought it worked great. It matched very closely with my P1 pedals when calibrated. It did seem to deviate once you start getting closer to 300+ watts though. I believe the inride registered lower than the P1.

Calibrating was simple, but to make things easier, I always left the flywheel in the same position and deflated the tire after each use and reflated to the same psi. I would still do the 10 min calibration, but only because it gave me an opportunity to warm my legs up.

I was able to easily connect it to my iPad via bluetooth and use their Kinetic inRide app to do specific training sessions that are preset on the app. As for quality, mine quit working after 1 season. Changed the battery multiple times and tried moving the battery contact pieces inside the inride, nothing worked. I emailed tech support at Kinetic and they never responded. I've considered purchasing another one simply because I have 2 bikes I use and don't care to swap my p1 pedals over to my road bike.
