this be a extremely well-designed and well-built sander . I have use many sander and be disappoint by poor design and bad belt-changing clamp system . its variable speed eliminate the need to press harder or softer on the sand surface , cut down on the chance of gouging material or cut divot in the surface . change the belt be easy : pull on the side lever and the belt slip on and off . there be a belt alignment adjustor which I set the first time I use it and have not touch since . the front handle be removable for sand up to obstruct edge . the dust bag actually work , and the sander can be hook up to a dust collector . most importantly , there be two accessory for the sander which make it versatile . the sand stand turn the sander into a upside-down bench-mounted sander , and the optional fence provide a way to easily and accurately sand endgrain on wood . it be build in Switzerland and it look and feel like it be make by swiss watchmaker .
