Small keyboard - Large input help

This keyboard makes particularly the text input and the use of smartphones and tablets in general; go especially if no desk can be used. Fingers crossed is called for, to write with this keyboard, but for my taste it is much more pleasant than long texts by touch screen input. And an Android device even has a mouse cursor that appears automatically when built-in touchpad keyboard is used. Clever idea. This allows the smartphone really operate entirely from the keyboard, the phone must be not to touch it. In all the excitement but still some little to be desired:

- The pressure point of the keys is a little hard;
- The shift (Shift) key should be clearly distinguished from the surrounding other keys;
- The touchpad responds sometimes only on very strong activity;
- The manual in PDF format would be helpful.

Overall, a highly recommended product, after a long search an input help for the move - "That isses".
Tested with smartphone Samsung Galaxy S 3 Android 4.1.2.
