I do not have particularly high demands on a keyboard. I do not need a thousand Keys with special functions or similar .. It would be nice if the keyboard somehow works reliably. In this model, the space bar was broken in less than a month. I must take in "right-angle" and partly to press to three times, so that a space is input the key now. I spilled any liquid on the keyboard, it is not fallen down me, I have not pressed too hard on the keys. Thus a defect after a short time is impossible.
