sometimes I order 50 of these. 2-3 will not work. 2-3 will not have working compass sensors. 0-2 will have "missing axes" for one or more senors. 3-5 will have unacceptable high accelerometer bias, 15 will have acceptable bias but I prefer to discard them in case of software upgrade of pypilot the accelerometer bias calibration will require redo.
If you want 3 working I suggest order 10
