I buy a 1274dv a few year ago . as I have find with other Bosch tool they be hit or miss . you might get lucky . you might get a lemon . my sander be worthless . I get about 2-3 hour use out of it . the paper will not stay on no matter how much time I or anyone else devote to try to solve the problem . I replace it with a Dewalt . I keep the bosch on a pile of junk in my shop to remind I of the problem I have have with Bosch tool .
