Review on 🔍 Smart Weigh GEM20- 20g x 0.001 Grams, High Precision Digital Milligram Jewelry Scale with Calibration Weights and Tweezers included - Ideal for Reloading, Jewelry, and Gems by Brenda Sanchez

Scale seemed to work well on first use. The second time I used it, I noticed quite a large drift, which was confirmed by the calibration weights. I weighed about 20 powder loads and confirmed on another scale that I know is accurate. When tested, the weight varied by up to 2 grams. I've calibrated the device according to the instructions and it's still not showing consistent weights. Calibration weights of 10g indicate approximately 9.4-10.9g between successive weighings. That's a 1.5g difference in real weight. For reloaders, this corresponds to a difference of 23 g of powder charge. Obviously dangerous. Buy the best rechargeable scale and throw it away.
