The reviewer who said the adjustable knob on top (which should increase stability around the eyepiece) is telling the truth. That doesn't work at all. In order for this product to be useful, you must be able to adjust the distance between the camera lens and the microscope eyepiece lens. Because the grip is not designed to tighten and stabilize, your only option is to position the camera lens flush with the scope lens. Much less than ideal. Super screwed up. The hunt continues.
