Did the keyboard for a few hours and would buy me defenitiv again. I have very large hands (1.95 am tall) and can really achieve and press, without which I push several buttons simultaneously each key well. As the previous speaker has said, you have to calibration needed the Touch Pad function only, otherwise the mouse of a jump to B, have also only gedeacht, verammt broken, but read just once INSTRUCTIONS. Short, it is a perfect keyboard that is verabreitet quality and brings the desired effect -> no sentence of more than 2 minutes takes to write. In conclusion: If you are unsure you can buy loose and will look forward to a top keyboard!
