"Now have probably all manufacturers offer keyboards" I thought when I saw this. Experiment as I am I bought a. we delivered the keyboard in huge package that looked more like an expensive necklace. Inside everything well packed with foam, I guess, the packaging costs already alone 10 EUR. The keyboard is very stable and rigid, the keys have a short stroke and are always palpable. 4 additionally supplied rubberized keys can be exchanged for WASD using the tool supplied. The keyboard has 5 (x5) macro keys, a sensor-volume control and 2 ext. USB sockets. The (unscrewable) palm rest is very broad, but enjoyable. The included software allows the GHOST (25) Macro keys Programming good. The lighting can be switched on and off by means of a button. As far as the keyboard would 5 * value, unfortunately there is compared to MS Sidewinder X4 some minuses: the lighting must every time the PC again are turned on, the brightness is too low. The volume control does not work 'idiot proof "Macro programming of MS is much better here by drag-and-drop but simple conclusion:... As Office keyboard is top, as a gaming keyboard mediocre one can not have everything!
