Review on High-Precision Milligram Scale: 50 x 0.001g for Reloading Gunpowder and Gemstones, 771 x 0.02gn Accuracy, Calibration Weight & Accessories Included, Multiple Units by Kristen Smith

This is another scale with a tare problem. The unit will normally accept tare weight, but if you are only pouring in powder from the 0.00 grain gauge you can add and add and add until the bowl overflows and still reads 0.00. It looks like they didn't test the firmware very well before deciding to ship it or qualify it for reboot purposes. So if it's wrong, what else could be wrong? The consequences are too great to risk. There are better options and I don't know them all, but I can vouch for these.
