I used this to sew 1/2 inch mesh from wood framing chicken coop hardware. It worked great once I knew how much force to use. It is not jam proof, but jams are easily cleared by loosening the screw that holds the staple holder. My goal isn't always the best, so I spent a lot of staples, but this tool is still better than my electric stapler, which doesn't insert the staples deep enough, or my manual stapler, which requires precise placement and is tiring.
