I used a toy magnet as the stirrer - as the video shows, it stirs well. It has cracks in the top plate but it does not affect the function of the unit. Please see pictures and video for the best description of condition. Note this model has a cylinder opening and tightening screw in the back that allows for a support rod to be used.
