I read the table from the link you posted, and noticed that the support for some of the 3d connexion devices ended at the same day of their manufacturing (or whatever the “product availability” means). In the case of SpacePilot, its support ended 3 years after manufacturing has ended, which is way too short since people and companies buy these expensive devices for work and rely on them to be functioning for as long as possible.
The SpacePilot that I have works extremely well, with perfectly stable tiny dead zone, and in excellent technical condition despite its age. It’s rare in this day to find a device that’s made with such quality. Sadly, it’s the software (plug-in) that prevents it to be recognized by the more recent Rhino updates.
On the other hand, as I mentioned in an earlier post, newer 3d connection devices have a giant dead zone and that’s what made me stick with my SpacePilot. Last year I was forced to buy SpaceMouse since SpacePilot stopper working with newer Rhino, and was so disappointed by its dead zone that I sold it quickly after. I also tried the more expensive models, and they also had that giant dead zone…
