Reliable function with small flaw

This product I've tested with 2 different operating systems: Android (especially 4.0 and above) and Windows. 8
In both functioned both keyboard, mouse, and special keys such as buttons for volume control.
Once the initial setup is done, the device connects quickly with the smartphone / tablet.

The only downside for me is the rather hard pressure point of the keys. Therefore, you should not expect so fast typing as on a screen keyboard. But along with the touchpad there is a practical combination that is another reason why I like it because the right and left mouse button is duplicated in each case, even on the top corners, and even below the touchpad. Thus, you have the choice whether to control the mouse with your thumb or with eg your index fingers.
Except for the pressure points of the buttons but I have had no problem with it, the thing works easy and despite the dimensions a robust impression. Versatile, it is in any case, whether one uses them to control the music on the mobile phone or presentation: This thing can do pretty much everything, although not as efficiently as a full-fledged keyboard and mouse.
Should resort to a "large" keyboard Who typed much so dear.
