My review of the 3D Connexion Space Navigator. In short good hardware, crappy software.
The Space Navigator is a 3D mouse. You can navigate through 3d worlds with it or you can rotate, pan, zoom objects while designing them.
My biggest issue with the Space Navigator is the lack of support for software. You are limited to what 3D Connexion says you can use. If your software is not supported you cannot program the movements (like a game pad with games)
Very closed software
I recommend the Space Navigator if the program you want to use is supported. Don't fool yourself into waiting for support. 3D Connexion's programmers have failed at programming software.
Where to get it:
