Got product. Proceeded to load batteries in all parts to full. Downloaded software. Tried to connect (usb) to reciever. Does not work. Crap if you use a Mac, do not buy!
I've been working with computers since 1994, and this is the first thing I haven't been able to connect/working on a Mac.
Windows seems to work so, if you own a Mac, be prepared to buy a Windows computer just to get these things to work as you want them to. GO II are now on my crap pile of things that just doesn't work with everything else i use in my workflow.
