Impressions leave much to be desired. I did not expect, of course, that the keyboard for more than 8 thousand can serve so little with careful use. I absolutely do not recommend buying. Has some pros: Ease of printing, materials, for the first time a comfortable brush rest. With its cons: She worked for 2 years and critical double-clicks or even keys appeared (left shift, control, alt, sometimes Z and right inter, arrows, "+", and sometimes the whole numpad) did not respond to pressing (only every tenth was registered).
