One of the best tool i have purchased, i just finished patched and sanded 4br house wall by my self, the package included 6 sand papers which was enough for me. And the LED light is soooo bright alow me to see every tiny scratch on the wall, but Don't expecting this sander is totally free of dust of course you will need respiratory mask and goggle and you will still need palm sander to sanding the corners and the edges of the wall, my only complain is the motor mounted on the side and not on the bottom this sometimes created un balance to the sander and leave deep scratch on the wall so i have to keep pressing it a little, 2nd no matter how hard i tightened up the bottom pole but it was always lose.
