pro : it be light weight make it good for vertical or overhead sanding . dust collection be good as long as it be not clog . con : switch quit work after 3 month , under warranty i should have have it replace , instead I think the same thing would happen again since it be the dust from sand , so I install a toggle switch instead . variable speed make little difference to speed , I bring it in for service think it be defective , no it be fine . dust exhaust clog easily and be hard to clean out . Belt removal be difficult , just make sure you do you bench curl everyday . Motor will not hold up to heavy pressure . would help if front handle removal be tool free . Summary : the most overrated tool on Amazon .
