Very nice quality unit. Watch my video review for a full overview, but the bottomline is that this is a really high quality unit, from my tests its very accurate (I used U.S. coins to check and it was accurate within 0.01 mm (and for all I know the coins may have been imperfect).
This will give you accurate and reliable results on just about any use. External measurements, internal measurements, or depth measurements all work very nicely. Comes with a hard plastic case. Comes with 2 batteries (one is an extra battery, nice... who does that?).
Well made, accurate, thats about all you'd want.
