Bought in June 2013, this keyboard. After just a few weeks the ESC button is broken. In normal use, the holder of the button is torn (Looks like cheap plastic made) and the button can not be used permanently. I have to keep the keyboard at first, but it happened after some time when more and more buttons. Now I have exchanged the keyboard. If the keyboard inexpensive materials would not be used in the buttons, I would buy me but again, because the stop point and feeling when writing and playing is really top.
