Keyboard with a high frustration potential

I never imagined then the keyboard ordered on the Internet, and was initially very pleased with the great flat design and the touch pad on the right side. The joy, however, then gone very quickly in practice used. Here my Pro / Contra List:

Pro:
- Great Design
- Innovative Touch Pad
- Pleasant keystroke point
- A cursor ball and 2 mouse integrated into the keyboard

Cons:
- Touchpad is immature and can not be nearly as precise and quick serve as an analog numeric keypad. The volume control can be operated only in broad intervals.
- Low battery life, so the keyboard most of the time also depends on the recharger. The surcharge for wireless here so does not pay!
- At average battery level, the entered commands are not recognized correctly, and you have up to 10 times type a word partially consecutively or very slowly, because otherwise several letters are easily swallowed. Very very annoying !!

Conclusion: The keyboard is something for the eye, but not for de Prxisgebrauch. Who design higher estimates than the frustration he has Daduchus who can confidently strike here. All other vernüntigen people should rather be de inger from here. (The conclusion was written unchanged to enter Beiiel for how the letters simply not recognized / swallowed.)
