I have to correct myself. I have the "trash" will not be returned. My wife who has a very bad eyesight, wanted to keep the balance, because they found the large viewing windows well. Inaccuracies she wanted to accept. So I kept the balance. Well it turned out after prolonged use, the scale over time - what a miracle - no readjustment back to the zero position declined even though they had been moved a little. Given the scale is on a horizontal base. I can only explain so that the spring parts of the scale a bit of time need to be "relaxing and einzuspielen" to. Anyway, she now works correctly. The weight display is accurate. I have tested this with certified weights. Of course, but you have to accept a tolerance of about 500g. Who wants to have it precisely has to rely on an electronic scale. For our needs, it is sufficient and I had an electronic scale. Be assured also because there are problems. In retrospect, one can say that value for money is quite good. So why only two stars? Now therefore because such supplement was necessary at all. Because you look at the Einjustierung the balance with the wheel still can break almost the fingers and because no mention of the possible initial problems on the package insert. The company does neither himself nor the customers a favor. Who is not so generous and patient as my wife does namely what I wanted to do initially - it returns the product.
