Pretty easy to use and worked 02/11/2010Cue Doctor Dent BufferI dinged up one of my favorite shafts pretty well with lots of little dings (I didn't know it was rolling around and hitting things). Despite sanding and polishing it I could always feel the little indentations. After working the shaft for maybe 20 minutes (had lots of dings) it had smoothed them out without removing material from the shaft. It even worked well on another shaft where I had a deeper ding. It's tiny should fit into any cue case and can be used at any time - ie - between matches or even between shots.I would recommend this product to a friend.
