I bought this set of cal. weights since there is no scientifical reviews for cal. weights. If you dont deal with drugs, these are very useful for common purpose scales. I had my brother weighted these weights by using an analytical laboratory scale. One of the weights, which is 10 grams, is exactly 10 grams while others have some error. I shared the results in a table. Here you go. For banggood: I would have paid extra 3-5 dollars for a one with wooden ( or at least plywood) case.

Товар пришел быстро . Качество соответствует цене ))) . В целом неплохо функцию свою выполняет . Гирки весу соответствуют . Из минусов плохой некачественный пластмассовый пинцет .

I received this weighing box and immediately used to calibrate all my weighing machines using these weights. I compared it with very high end machines and weights are really calibration standard. Only problem was I received with box lid broken. Luckily no weights were lost. I think that was due to weight of the steel weights and box cant take that kind of beating during shipment. I would advice to go for better box of may be a wooden box.

They are very cheap, made from plastic that is very pliable. Not all the very tiny square weights fit in the rectangular holders; you need to slightly bend them once to make them fit. The lengthy shipping time
