This is an exceptionally good, top quality piece of gear. Paired with a Wolverine jig, it's quite possibly the best sharpening system for woodturning and other tools on the market, bar none. For comparison, I consider it a substantial upgrade from the Tormek system I used to use, both in capabilities/flexibility, and in ease of use--and that was after I refitted the Tormek with a CBN wheel. I can slow way down almost to Tormek levels, or speed up to reshape a lathe tool. The combination of variable speed (ranging to very low), high quality CBN wheels, and first rate build quality/fit and finish put it above anything else. If you have an investment in good lathe tools, especially with powdered metallurgy high hardness steels (Thompson, Glaser, etc.) it's really worth considering.
