I knew the release of this brandnew mouse couple of days ago but the offline retailers in AU don't in stock of it at all. I tried to wait but the old one died tonight. I have to find a new one to replace it asap. I've just paid 4 it and waiting 4 the delivery now. If it arrives in few days I'll be the fan of this website. . . . Unbelievable!!! The DHL arrived this morning!!! From Auckland to Sydney!!! Just 1 day's waiting!!! Gosh this website is so fking awesome!!! And the mouse is much more better then I expected! Two awesome colourful lights! The powerful software driver! This is absolutely my happiest online shopping in AU!
