Functionally, the heads fit and operate well. There is however, a design flaw with the slot half way up the head. Under certain circumstances, the soft tissue around the mouth can be drawn into the slot in a “pinching” action that is mot unpleasant. This does not happen with the “name” brand and for this reason I would not purchase this product again.
