Now why would go disparaging something with no practical experience using it? That's not helpful. The Neoruler is expensive, but I got lucky and found one unused on ebay for stupid cheap... Cheap enough that I didn't mind spending a little more to buy the caliper addon from the manufacturer. It's not a gimmick, it's professional quality and it's spot on. Accurate down to. 001, metric, imperial, fraction. It's not cheap but it is cool. Do you need one? No, but I'd venture there is a lot of stuff in my shop I don't need but I'm glad I bought and that I use. Your mileage may vary.
