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.

Son muy baratos, hechos de plástico que es muy flexible. No todos los pesos cuadrados muy pequeños caben en los soportes rectangulares; es necesario doblarlos ligeramente una vez para que se ajusten. El largo tiempo de envío

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
