3Dconnexion SpaceMouse Enterprise Kit 2 with multi-function buttons and 3D navigation. I used it for BIM for 3 weeks, but I'm selling it because keyboard operation suited me better. It's very expensive, but it seems to be essential for those who can use it. It's a limited edition and you can't buy it anymore unless you search for stock. All accessories, including the mousepad, are included. - Model Name: SpaceMouse Enterprise Kit 2 - Accessories: Mouse, SpaceMouse - Package: With original box - Color: Black - Features: Multi-function buttons, 3D navigation Thank you for viewing.
