Also, my balance was initially a failure, the test results were not reproducible. Unfortunately I have turned myself to the manufacturer. The scale was quickly exchanged for an intact specimen, but conversions are made through Amazon is recommended because the manufacturer the cost of postage is not refunded, Amazon but everything unwinds free. After prolonged demands of manufacturers were too accepting tolerance range of about + for this scale - to 5 g. If you want to weigh 20 g, 25% error are very much if you want to weigh up to 15 kg about 3 parts per thousand are very little. This is certainly in order, of this fact you will not elucidated in the product company. Because of me not not entirely satisfactory appearing quality control (other reviewers complained about similar error) and was not sufficient product information there is the point deduction. Design, operation and range of scales are very good. New 2014: With a digital display, I expect, if no closer indication is given with an accuracy of + 1 digit, so here + - 1 g as actual accuracy has been found that this accuracy is achieved reproducibly (control with calibrated scales of post at 20 g. and with 100 g calibration weight Display 20 g or 100 g). Only Soehnle will not guarantee well. But in the sense of appropriate consumer information, I think an accuracy specification necessary for a meter for sure. Since it still lacks only 4 stars. This is a star more more than before, because the scale has proved to be very accurate.
