I be on my second unit . the first last about 5 year of moderate use in finish carpentry , include occasionally heavy duty use . I frequently use it for scribe cabinet and trim , and restore door and sash . durability be not what I typically expect , but the overall design be so good I do not look for a different one . pro : Lightweight durable , powerful motor dust pickup good with vacuum attach -lrb- also material removal improve - less clog of belt -rrb- Belt tracking compare well to other I have use - no belt destruction while focus on the work Table top use be great for a variety of grind task , include initial phase of re-sharpening nick chisel -lrb- use water to keep blade cool -rrb- con : Power switch be more feature load -lrb- variable speed , lock on , and adjustable maximum speed -rrb- than heavy duty - my second one be fail now dust pickup get clog when sand finish with just dust bag , not vacuum attach . it be difficult to clear it once clog . dust bag be cumbersome and easily broken have recently refinish a softwood floor , detail with both this and a heavy Porter Cable unit , I can see the value of a heavier sander , but only if you be sand level surface .
