I get my sander this past Monday ... I can not keep my hand off it ! it be already set up with 80 grit ... all I have to do be place the collection bag on top and plug it it . she run so quietly yet be so strong . the dust collection be wonderful , there be virtually no dust in the air ... or on the wood . I have be reclaim some 4x10 pine beam that be totally destroy by sun and moisture and have be wait for something like this sander to come along for the past 10 year . I change from the 80 to 60 grit ... and could not be happier ! I be use to my Craftsman 21x3 which be so loud you need ear muff and be so difficult to change belt that you avoid it like the plague . this Makita be just the opposite , quiet and belt change be as easy as pie . I just wish I buy this a long time ago !
