Starrett's Last Word is likely the weakest product they have made. I don't know squat about the insides of test indicators, but there must be a design glitch. Every Last Word I have layed hands on, maybe a half dozen or so, has been awkward with less than good feel in how fast and repeatable the needle goes back to zero. Anything from Switzerland is likely better as are the instruments from Germany. 312-b is my workhorse test indicator, but I also have other Euro indicators, they are certainly worlds better than the Last Words I have seen.
