Review on Rockwell RW9138 Sonicrafter Sanding 20 Piece by Robert Cartwright

This product is a complete waste of money. When I tried this product from the industrial and SCIENTIFIC category, I found it to be too rough on the surface leaving scratch marks that are hard to remove. The sandpaper disc keeps coming off in the middle of sanding, making the whole process frustrating... The only pro is that it comes with various grits, but that doesn't make up for the poor quality. Overall, I wouldnt recommend this product to anyone looking for a dependable and efficient sanding tool..
