>>1014217its a mouse that is built for moving around viewports in 3d space, fantastic for its purpose, but almost everything we do is going going to be sculpting related, where we have tools on our pen and keyboard/macro pad already for this, or we are box modeling, where again, we are not going to be using this to its maximum effectiveness.
if you want it, go for it, but for 180-400$ I would never consider this, I would never consider this.
I would instead just get 3 rotary knobs on a macro pad, and have each one assigned to rotating an access with a scroll wheel to move me in our out. hell a tour box could do this with one knob if you map it right and would be more useful as a macro pad.
