A real pain
"The TS-2.3 has some nice features, but they are completely diminished by the inaccuracies of the gage. I spend HOURS setting up my truing stand only to discover that the gage was incapable of holding true between various wheel diameters. Without giving up on the tool, I painstakingly disassembled and reassembled the stand to precise, relative dimensions and was ultimately able to get the stand to hold "true" within ~1mm across wheel sizes. This took multiple afternoons of frustrating trial and error to finally get it right (all while the Park Tool support was claiming that I am demanding too much from the gage) ...but at almost $400, I think accuracy should be expected."
