This is a great scale for its price but it is not a scale I would bet my life on measuring out 1 mg, period. Take the extra time to volumetrically divide a larger sample by solution or buy a .00015-gram range balance if that is your intended use.

Scale is far better than I could have ever expected for this price. It is accurate, precise, and the readings are repeatable over a wide range.
It includes all needed accessories, the case is excellent and holds everything firmly in place.
The calibration weights are accurate (some reviewers said theirs were not solid but mine were).
Great selection of modes available, just be careful not to mix up oz and ozt.
Highly readable screen.
