I love the 3DConnexion Wireless CADMouse but the universal receiver has to be no more than 3 feet [92cm] away from the mouse or else you get a very jumpy mouse cursor. I’ve tried everything to correct the issue but I found that distance matters. The Bluetooth connection option is better performance but the mouse goes to sleep and you need to shake to wake it. This gets rather annoying doing this every time you stop using the mouse for awhile.
I’m hoping we’ll see a software update to fix the few glitches. Until then, the receiver will be just a few inches away from my mouse at all times. Wireless… but truly not constraint free.
