3dconnexion SpaceMouse Wireless (3DX-700043)
Love it. Smooth and slow (good thing)
3dconnexion CAD Mouse (no wireless available at this time)
3 Mouse buttons + wheel, function button and forward & back button (all programmable)
I use the middle button for navigating and wheel (push down) for on/off snap.
In 3D you can move fast with CAD Mouse and fine tune (all directions) with SpaceMouse.
Excellent for the new awesome 3D animation feature 2016. Good job SP!
