I tested all five of the encoders and all were working fine. Not very high resolution, with only 20 pulses per revolution, but perfect for simple OLED menu control. I've successfully used them in multiple such projects.I prefer this style (threaded shaft with nut) as they're easy to mount in a box compared to the ones on a PC mount module.Great value at two bucks each, with knobs included.
