I bought this Logitech V220 Cordless Mouse to use with my notebook, obviously, since it was labeled a notebook mouse. However, using my broadband mobile internet connection, i encountered problems. The connection is either 3G or falls to GPRS in distant environments. The cordless mouse LOSES all response when the connection is GPRS. Apparently, the frequencies used by the mouse CONFLICT with the GPRS connection frequencies. But in 3G, also, although the pointer is responsive, there is 'noise' heard through my usb portable speakers, every time i move the cursor. The thing is that there is NO NOTE whatsoever by logitech on the manual or the box or elsewhere about these conflicts when using their mouse. And that is not OK.
