Smart Weigh High Precision Digital Milligram Scale, with Case, Tweezers, Calibration Weights, by Smart Weigh

This scale comes in a very nice black semi-hard sided foam-lined case with two 20 gram weights that are designed to calibrate the scale. It requires 4 AAA

batteries, which are included. The case even includes a space to carry AAA batteries so that you can remove them from the scale for storage. This would protect the scale just in case one of the batteries would start to leak. The case also includes a set a tweezers (and a place to store them). There is a set of instructions in an expandable mesh pocket in the top of the case.

The scale is very easy to operate but I did have a hard time getting it to measure 20 grams as 20.000 grams. I kept getting a weight of 20.002 and 20.004 grams which, in the scheme of things is pretty darn close, but it is still slightly off. It started off a little farther than that but I kept on re-calibrating the tare weight and eventually it got that

close. It could be that the weights themselves are off by that little bit - I wouldn't know because I don't have any other scale that will weigh as precise as this one.

It has a flip-down cover to protect the item that is being weighed. 

The scale measures in grams, ounces, carats, troy ounces, pennyweight and grains.

I rate this scale 4 stars out of 5. It is weighing off that little bit - very, very close but no cigar. If you can live with being off that little bit, this whole package is very nice. The scale feels solid, the case is impressive. It all looks like it was designed for somebody that knows what they are doing.

Note: I received a free scale from Smart Weigh so that I could look at it and try it out in order to write an honest review.
