Summary: PLUG IT IN AND IT WORKS, WE'VE BEEN USING THESE FOR SEVERAL YEARS AND THEY LAST. WE USUALLY ON BUY THEM TO REPLACE A DIFFERENT BRAND, OR WHEN WE JUST NEED MORE OF THEM. EXCELLENT BUY FAST SERVICE.
Summary: The product seems really good and I think it's worth the price. it worked exactly as advertised for me, except when I plugged it into my Mac. "No driver required" is true, but you do need to configure it as a keyboard in System Preferences which is missing from the instructions.
