I use this to move drywall and plywood when I have to move it any distance by myself.  The handle is angled away from the face of the sheet, is comfortable, and just the right length, leaving your other hand free to balance the top edge of the sheet.  I'd give it 5 stars if Stanley improved a few things just a bit: First, if they reduced the front-to-back depth of the bottom just bit and made the retention lip a bit higher, the sheet would feel a little more secure (it's not worth carrying more than 2 sheets anyway, as it becomes too hard to balance).  Second, if it could freestand a little more securely, it would be that much easier to get a sheet on the thing.  It's a pain in the neck when it falls over.  In spite of all that, it's still the sheet carrier I reach for most often.  Cheap, strong, and reliable.  Bright yellow makes it hard to lose, too.
