All I can say is Wow! I don't know I went so long being a Pro/E user without having a peripheral from 3DConnexion....you guys did a heck of a job!
It took me about 20 minutes of playing with it to get comfortable with all the range of motions (the sensitivity adjust button is a life saver!) and to be honest, I thought it would take a LOT longer! Now all I have to do is program in my bazillion mapkeys and I'll be good to go!
