Hmm... To be honest I can't really give you any insite on that. ^-^;
I don't really use wireless stuff.
And I just went to wal-mart and bought the most reasonably priced mouse I could find...
I think it was an iHome something.. I use it so much the print on it faded to an unreadable shade and some of the coloring is failing...
But as for functioning, I've dropped it a billion times and it still works fine.
