We bought the Garden Claw several years ago at our first house and never used it, because the handles are mounted for lefties.  That is, the two hand-grips are each curved to the side, giving a feel of turning a wheel when you use it.  This would be great if you put your hands on the grips and turned it to the right to dig.  But the tines on this gadget are positioned so that you have to "steer" the Claw to the left to get them to dig.  Since us righties have more strength in our right hands, it was very awkward to "steer" the Claw to the left.  We spent about 20 minutes with it in the garden that day and haven't used it since.
