Finally I decided to try the Copperhead, although was comparing it (online) with the G5 for past 2 weeks.
Kinda disappointed that it died on me less than 24 hours! It was working fine one minute and the next, it froze right in the middle of the screen. No matter how much I move the mouse, tried switching profile, changed USB ports, restarting my PC.. it just doesnt move more than a half an inch.
Oh, yes.. I installed only the latest driver from Razer, flashed the firmware (surprised that Razer's support section is down). And no, there wasnt any other mouse drivers installed cos I just did a OS install onto my new hard drive.
Is this normal? I hope my exchange to another one later will at least last me as long as my crappy Logitech mouse, which I am reverting to now after my spanking new copperhead bailed.
Maybe its just my luck
p/s it died when i was browsing on the Internet using Firefox.
