the Bosch belt sander be very powerful for it be size . I build a cabinet and use it to sand the wood , very fast sand smooth out the panel perfectly . I also have patch up my ceiling and it be uneven , this sander do pretty quick work of smooth it out . the only issue I have with it be the sand belt that come with it do not seem to stay evenly place on the roller . I can adjust it but it never sit the way it show in the manual . the belt always go outwards toward the belt release lever . I be go to use this belt up and then try the 3M one I purchase , hopefully these belt be better . but overall I be pleased .
