The only issue I've had was the battery was DOA, but there was a spare included, so it was a pretty easy fix... although the battery cover is a bit loose.  That said, mine does actually say "Neiko" on it, and it was cheap and it seems remarkably accurate.  Hard to complain much about this device that was relatively cheap.  Used it for various measurements where I needed +/- 0.1mm accuracy and seemed fine.
