I had been waiting for a wireless version of this trackball since I loved the old wired version but the wire gets in the way. This also works great with my Logitech keyboard because I only need a single usb port for the receiver. Good deal at Overstock.com as well!
just got this mouse yesterday, it's quick,responsive,clicks like a charm . some people claim it's a bit bulky and heavy. seriously? your hand rests comfortably on this mouse , no silly usb wireless receivers. weight is solid ,stays put . have you had tried those tiny mice, that get flung, or fall off your work area, when you accidentally nudge em? i've broken 2 sony vaio wireless mice because of their weight issues or lack thereoff. "love it" is an understatement. hooked on bluetooth mouse for life- at least for this one.
I bought this (and the others) because I thought my old mouse had died. After I ordered it I checked my old mouse on a different port-it worked just fine. This means that either the USB hub or the USB extension is flaky. I believe strongly in back up so I'll keep the mice I ordered.
