This keyboard microsoft and very pleasant to the touch. Pressing the buttons, it is not a hollow sound like the low-end keyboards. The buttons are thick, the springs are quality. Ergonomics is special but you get done quickly. There is a carrier to put his wrist and it is removable. I personally do not like so I removed. Some of the keys is raised, why not, I got used. There is a battery level indicator, a switch to switch the function keys to Windows shortcuts. The space bar is divided into two, one part after handling, can be used to rewind, I myself do not risky, I stay with my two half-bars of space. This keyboard also comes with a microsoft mouse without son. A single USB port for the 2 devices. The mouse is also very stylish and very well finished. The thumbwheel switches from left to right in order to paginate a document, that is very significant. This mouse also has, on the side, in the thumb, a soft button that toggles on Aero when you have several windows open. In short, only positive and quality. It lacks the ability to re-raise the upper part of the keyboard, with little feet as found on all keyboards except on this one, unfortunately. And battery 2 devices are delivered. No need for special driver installation when you have windows 7.
