It does help me as it is supposed to be. After few weeks using it I can use one keyboard and shifted between my home computer and office’s computer. My keyboard is nice mechanical one, so regardless the computer is, this keyboard helps me with my ideas flowing. UGREEN Sharing Switch does work - and HOPEFULLY KEEP WORKING LIKE THIS to have 5 stars. Package wise, it comes with two USB 3.0 cables - which is great from user experience perspective. imagine if you have to buy another cables?? The maker seems to give good thoughts on how users would be helped by this device straight from the pack. Well done. Keep continuing to make hi quality product! Deserve 5 stars.
