This product is almost exactly the same as the Ryobi BE231 it replaced, Externally the primary difference is a carbon pad to reduce frction on the Bosch. The Bosch cost twice as much, and became nonfunctioinal after little use, while the Ryobi model withstood heavy use for years. There was so much friction on the carbon pad, that it heated up painfully. The sander started breaking belts for no apparent reason. The dust collection on the Ryobi was not good, but it was totally nonfunctional on the Bosch.I have been satisfied with the Bosch routers (1613,1617), but their sanders, both belt and ROS, have not worked well for me.
