Review on QWORK Positioning Aluminium Woodworking Carpenter by Shane Schobinger

Products arrived without milled center slots. The holes have a recessed bottom and are designed for surface mounting. Not suitable for clamping corners as stated. The workmanship is good but the laser engraving has an error of plus/minus 1/16 inch across the scale. Some values are long, some short. Well, if you need an inside corner alignment bracket to screw to your countertop, it's basically useless for anything else.
