I buy the Bosch belt sander because , at the time , it have the best warranty . I plan to sand all the peel paint off my 1 1\/2 story clapboard house and repaint it . I think that I would go through at least two of these sander . I buy the belt by the case and spend several week sand the house . I would run this thing until it overheate and stop . I would let it cool down and go at it again . to my surprise , I complete the job and the original Bosch sander be still work good as new . I later find out that this sander be good for more delicate work . I have more control and it seem to lay flatter . it eventually die -lrb- smoke pour out of the motor -rrb- and I replace it with a Makita sander , a very robust and dependable unit . over all , I would prefer the Bosch for finer finish work and ease of use .
