Canon EOS M3 mirrorless 24.2 MP APS-C digital camera in the box with EF-M 18-55mm f/3.5-5.6 IS STM lens with cord and charger. Most of the time the camera turns on and shoots fine, see the test shots, but periodically it throws an Error 20 code. 

The auto focus works correctly. Aperture and shutter control work correctly. The camera shoots in all its modes. We have not checked every corner of the menue but everything we checked worked. The camera and lens are in clean condition showing little if any wear. We have been unable to get a shutter count on this camera
