Very solid build. Assembly quality and precision are generally very good, some minor misalignment's here and there, within 0.2 degree precision, but at extreme angles expect 0.4 degrees, I bought 3 sets, there are slight variations between them. On a fine tuned saw you can expect very high quality results with this Vevor miter gauge. The grater is extendable up to 35"/890mm that's very impressive. Simple repeatable cuts with the built in stop, which has micro adjustment. It can be difficult to read the millimeter measurement as it is partly hidden by the pointer, Inches are easy to read though. The pivoting screw in the angle meter, has a slight wiggle 0.1 degree, its as good as it gets with the design used. I would buy again.
