So comfortable and right in the display as a digital scale this is not natural. But if, for example, a letter about 20 g, 25 g or 50 g weighs etc., can be determined using this scale. Depending on the angle, the display shifts somewhat, because the pointer has some distance to the applied on the transparent plastic weight scale. Since you should stop at the 0-position of the scale (which in turn is customizable through a scroll wheel) play an appropriate posture and also best not to change this when weighing then great. ;-) To "calibrate" or Check function I have used in the absence of specific weights euro coins. According to German Bundesbank, for example the weight of a 2 coin is 8.5 g I have tens of such coins weighed together, and in fact:. The balance displays the total weight of about 85 g to. The balance is very favorable, and considering the price, the functionality is for me and for my purposes fine. If you expect more, is - I think - have to spend even more, for example, for a digital scale. I have my glasses and a 10-pack of paper handkerchiefs weighed in the balance, for example: each 25 g, however my key ring weighed more than 100 g for weights above 250 g you can not damage the balance due to a mechanical limit... Unless you look for example represents itself on it. Since I am not sure whether the balance would endure that. But I have not tried it myself, because a lot of sense would give no such test me. Because less accurate (angle problem) and a not so comfortable reading I give the balance 4 of 5 stars.
