The first impressions are not particularly favorable. Naturally, I did not anticipate the possibility that a keyboard designed for more than 8,000 people could be used effectively with so little data. Purchasing is not something that I would ever suggest doing. With its positives being: Ease of printing, high quality materials, and a comfortable brush rest for the first time ever. Having these drawbacks: She labored for two years, during which time vital double-clicks or even keys arose that did not respond to pressing (only every tenth was detected). These keys included left shift, control, alt, sometimes Z and right inter, arrows, "+," and sometimes the entire numpad.
