The keyboard is not bad per se. Unfortunately I have with my now and then a few deficits. When writing letters are sometimes for no apparent reason from 2x to 10x successively available. While gambling react now and then the buttons. I think that that is due to the radio transmission. The brightness of the keyboard turns repeatedly to maximum and can not also programming. But the built-in battery is in my view only rotten or the power consumption is too high. I very much from the sofa Zocke, come sometimes 10 hours together. Then the built-in battery is exhausted, and the PC It can also be not very fast charging. I had several times the power charger cable use, so I can operate the keyboard via wireless. I hope that the built-in battery is not as fast degrades, not that I still have to connect the power cord permanent.
