Real tool for those who work in 3D. Tested on Autocad, Inventor, Sketch up. Lumion does not support it.
Conclusion after 2 years of use: When you learn it, you will wonder why you didn't get it earlier!

P.S. It may take some time for some people to learn it. It took me about an hour

Unbelievable device for anyone working with 3D programs, CAD, design, etc. I have been using it for about 6 months on a daily basis at work.
Its responsiveness and accuracy are amazing. The two buttons on the side can be adjusted separately for each application and can have multiple functions each.
There are ready-made shortcuts for many major design programs, but the software recognizes the program you are running and creates shortcuts for it.
It is definitely worth its money, and the only thing I regret is not getting the Pro or Enterprise version, as the extra buttons and shortcuts would have made my life even easier.
