Overall, a great product as already noted by others. I would like 2 tips attach (to update to 8.1 and BIOS update): 1) in the device manager have been shown me 2 unknown devices. Despite automatic driver search that was so, so I downloaded from the Lenovo website a new system update, the old has been uninstalled, and then drivers and other updates were heaps downloaded and installed (900 MB)
2) the pin initially had no tenderness (Photoshop, etc.) to paint. To this was on the Wacom website a "feel Driver" - and happy you are with the wonderful paint with pressure ratings
