The accuracy was measured with the supplied calibration weight and to mint coins and their weight (eg 1 EUR = 7,50g). Thus the scale is very accurate and with the same range 0,1-300g very flexible (the second decimal place I have omitted deliberately, because not meaningful). For the weighing of additives of animal feed very practical. Only the ambiguous advertising Amazon since the purchase of this part is a little irrtierend. Because no, I do not smoke; and yes, I am an animal lover, the blending together its food responsibly yourself!
