Compared to the 1x30 inch sanders on the market, this seemed to be a better, more robust solution. I wasn't really expecting to need to do so much "fiddling" to get it right, however. Initially, I was disappointed that the literature indicated a TEFC motor, yet this does NOT have one. The drive belt supplied had an awful "knob" at the seam, and caused way too much vibration. Grizzly support was very good, however, in helping me with replacement parts including the disc that stripped the set screw threads immediately, and a much better belt, that unfortunately, could not be used since it was too short to fit. Ultimately, we needed to arrange for a longer (non-standard) belt, whereupon EVERY piece of the sander had to be re-adjusted and fine tuned to make it fit. The sander does now seem to be working properly, but be prepared to do some fine tuning.
