I need to resurface a cupped and warped porch deck , a bigger job than my pc rotary sander could handle . I decide on this sander . I initially buy a Ryobi from Home Depot figure I would not need to use it a lot , but then return it unopened after I picture myself use a break down crappy tool in a couple year . after read many review I decide on this sander . I be really happy I pay $ -lrb- ... -rrb- buck more for a much higher quality tool . track be perfect . power be very good . dust collection be UNBELIEVABLE ! after a few minute on the porch I realize there be not any sawdust , yet the paint be come up . a few more minute and I check the bag ... the bag be nearly half full ! it capture almost everything ! I love this sander ! this be one of those tool that you will be happy you spend a little more money on and you will use for many year to come .
