Another new keyboard for 15, - I have already disposed of in the recycling center. This rattling device was unusable. The keyboard of Geemarc is top notch. It is stable, wobbles and does not rattle when writing. The inscription of the numbers and letters is 1 cm big and catches the eye. One look and you have everything in sight. The stop is muted, you can write on the keyboard well. No expensive scrap. What I also find is good that insertion and removal is superposed, as start of a line and end of line.
