I bought the scale to determine whether my letters each exceed the 20 or 50-gram limit to then stick on the correct postage. The delivery was prompt. The scale comes with a letter pad and a practical shell in which you can fill with bulk material. Unfortunately, there was no guidance on the scale that I would have wished for Enstellung the balance. The balance must be adjusted when switching from the letter pad to the shell, since both different weight haben.Zum einjustieren there in the back of a scale of a Justierrädchen respectively. I have the scale adjusted with coins (1 euro = 7.5 g, 4 x 1, EURO 30 g, 20 cents are 4.1 g, 2 Euro are 8.5 g). The scale starts but only at about 10 grams to move in. From about 15 grams of the weighing result is then halfway useful. The 2-gram scale can be read only with a magnifying glass and not in any case make much sense at the lack of accuracy of the scale. I had imagined a scale that up to 50 grams is quite precise in the lower Wägeberich, but in retrospect, I realize that, can not be expected from a simple spring balance, which has a weighing range from 0 to 250 grams. For my purposes it is sufficient just like this, although I can not be sure in the area to 20 grams, if the letter weighs just under or just over 20 grams. The price-performance ratio is reasonable.
