Review on 🔬 Hestya Digital Balance Tweezer Test Kit - Calibration, Measurement & Inspection by Alexander Scharon

Here are some of them from Mettler Toledo. found that the worst weight was 2g, which was 4mg less, and 5g was 2.9mg less. 50 g less by only 0.1 mg! The rest was good too. For €12 including shipping, that's a good deal. If you want precision weights, they cost hundreds of dollars. Look for something like F1 class or better and be prepared to pay a lot more. Anyone posting about it and trying to measure their accuracy with a $25 DMS pocket scale is probably way off the mark.
