have now own this sander for several month I be not as happy as I have be . you have to be extremely careful when use this with a sand pad . if you catch the pad -lrb- even lightly -rrb- you ruin the sander 's ability to track . I have send it in for repair once already and have to do so again . the sander be not nearly as durable as I have hope and I be very careful with my tool . I recently buy a Makita which I find to be a much better sander . I have be generally happy with the purchase of this belt sander . I have find the variable speed to be a nice feature and power be not lack . the base plate be not cast aluminum but the graphite platten plate appear to work fine at reduce heat buildup so I be not too worried about warp . the cloth bag be not as show in the photo , view the part diagram for this sander on the Bosch web page explain the change . the dust collection work well provide the duct remain clean -lrb- mine packed full within a few minute of sand pine at 50-grit -rrb- I have to completely take apart the sander to clean out the duct but it appear to work well now .
