I still have old weight such as one used in the labs there 40 years. It gives accurate results but for those who want to win "Master Chef", it can be wrong in two three grams when the weight is more than 2 kilos. In fact, it is extremely accurate (risk of error less than 5%).
As with any food balance, it is possible to tare. The buttons are touch-sensitive, it is best to design but more brittle with use. That said, I have this balance for over a year and have not encountered any problem.
To note, it is very important to me, that the surface of the scale is easy to clean. Indeed, it also serves as my weighs letters ;-)
A default, which is found on all scales culinary small: Reading, when weighing large containers, requires qualities gymnast and an archaeologist lamp (laughs): you can not see the numbers . Moreover, it is sometimes difficult to put into balance on the balance of large dishes which led me to buy her big sister Soehnle - 6208315 - Electronic Balance - Plateau Silver / Black - 10 kg / 1 g essential for family meals .
In short, an excellent product, reliable, I recommend without hesitation.
