Review on 10mg/100g Precision Stainless Steel Jewellery Calibration by Desmin Dickerson

Half of the big weights are 0.1-0.3 mg behind, the small weights are much worse. The pair is 25% cheaper! Quality just doesn't exist. Manufacturing is missing. burrs on metal. the shapes don't fit in the corresponding compartments, the box is also kind of crappy, the weight cover doesn't close, the tweezers aren't precise enough, can't hold half the weight because the tips are too thick and rounded.
