The picture on Wissota's site shows a diamond dressing tool with a label on it that has graduations. Maybe yours was an older model or the diamond wasn't original. I'm surprised to hear that you think the Wissota is junk, that would be the first time I've heard that. Of course, most people that have one are probably only experienced in using one machine, so compared to nothing they think it's great! I'm not biased in any way, but I'm looking to purchase a machine very soon and I'm doing all of my research now. Thanks for the replies so far.
