I purchased this sander 3 months ago and have used it regularly. I previously owned a Delta Drum Sander but when I needed a part it wasn't available because Delta doesn't make them any more.
I am delighted with my FLAT MASTER SURFACE SANDER. It easily flattens a warped (twisted) board and you can then run it through the planer and it comes out even thickness. As for repairs, the FLAT MASTER SURFACE SANDER is so simply constructed there is nothing that can go wrong that you can't fix yourself. There is just a motor and a drum set in a box and that's it.
I could have saved a whole lot of money if I had bought the FLAT MASTER SURFACE SANDER instead of the much more expensive Delta.
I recommend this sander to any woodworker or wood turner. (Posted on 9/22/16)
