Best quality. I have three of these in my shop - the rest have been in use for over 25 years. I couldn't remember any Remember problems with previous installations. I don't understand what is wrong with the setting. Mine was ready and working in 8 minutes! Drill 4 holes in a 3" workbench. Insert the carriage bolts into the holes. Assemble the Place a new vise on a bench or large box under the workbench and add washers under the vise until the vise rises --- to where it needs to be fastened. Slide nuts onto the ends of the carriage bolts. THAT'S IT. 2 You certainly don't need people. As I said, 8 minutes. I calculated the time based on comments on the complexity of the installation. It's heavy because it's made of steel eh and underneath needs to be supported before you can put the nut on the carriage bolt, but it's easy to lift with washers. Your grandchildren will use this vise. Excellent quality.AY
