This is a replacement for an older version of the Sculpt that gave up the ghost after a few years. Great feel. Paired with little problem. I use it with Input Director, cableless KVM software, and it works great. My only question is that after several weeks of use it started vibrating today. I don't have any specific software installed for the mouse so I'm not sure why all of a sudden today this started. The primary system is a Lenovo laptop in a docking station running Windows 7 and the other 2 are Lenovo's AIO running Windows 10. On the Windows 10 system it is refreshing the page when it vibrates and on Windows 7 it's doing an Alt+Tab.
I needed a new mouse for my PC and I wanted one that is wired to my USB port and comfortable to use. This is perfect for my hand and is easy to use. I didn't need instructions to use it as soon as it arrived.
I had been waiting for a wireless version of this trackball since I loved the old wired version but the wire gets in the way. This also works great with my Logitech keyboard because I only need a single usb port for the receiver. Good deal at Overstock.com as well!
