I have used the Gorilla Gripper for a couple of weeks now. It make carrying sheet goods much easier. It grips very well when used as directed. Example: With a piece of sheet goods setting on the floor on the edge, place the gripper half way of the lenght, pick up as shown on the instructions and you can easly carry the piece with one hand. Money well spent, especially if you are working by yourself or carrying 3/4" sheet goods which are heavy.DLB
