The control buttons operate by touch. Links is the power button. Press once briefly and the balance to go, press and hold and it goes out again. After about 3 minutes of non-use it starts from himself. She turns on not by itself when something is on it and you can turn it off manually, which I find very good. Can weigh grams (up to 5kg), and centiliter deciliter. The Tara function it also. With this you can fill all the ingredients in a bowl and set for each ingredient the scale to zero. Lined it is powered by 2 AAA batteries which are included. I like better than lithium batteries, because the simple, I have always in the house.
Very convenient ... from behind you can pull out a rakes and hang them so to save space somewhere. Compared with my old scale shows always 1-3g on more weight. What weighs on both right now I can not say but 1-3g are also bearable.
A good and easy to clean scale for which I would like 5 star forgive.
