   I've evaluated five or six of these.  The accuracy and stability of 
these things, especially in the face of temperature variations, is utter 
crap.  Don't ever adjust a +5V supply in a PDP-11 using one of these. ;) 
  Some of these were tested as being 15% off, measuring nearly six volts 
from a (very tightly calibrated) 5V supply!

   Buying cheap multimeters (or any other tool, really) is a false 
economy.  My daily-use handheld DMM is an original Fluke 77 (no suffix) 
that I stole from work so long ago that I don't mind mentioning it here. 
;)  I've had it for almost twenty years, and it was well-used when I got 
it.  It works as if it were brand new.
