Now, if this device could only make a 4X8 piece of 3/4 inch ply lighter, it would be great. Unfortunately it cannot. But it can do the next best thing. Instead of having to push your ply along the ground and hope you don't hit a crack or get stuck on something, this deceivingly simple , but well built device lifts the panel off the ground for easier maneuverability. The body position when lifting is also easier on the back and shoulders, then trying to jerk it around. It's well built, but I think a bit overpriced.
