What is it actually about thät G1 ? Some display it as a 800 DPI mouse, others as a "new 100 DPI" - mouse. Was researching on how to distinguish these two versions or where to to get the 1000 DPI version of that mouse. Even called Logitech, but they didnt know anything about a "bränd new Version" X_x .......
The 800dpi G1 is blue whereas the Korean version of the G1 is silver and has an "updated" 1000dpi sensor. The ones you will find on ebay will be the 1000dpi version.
I've ordered one to see how decent it is. The last 3 razer kraits I have bought have been from Korean sellers and all perform as well as the ones produced by Razer.
Although I think the scroll wheels are cheaper or at least them seem to come lose and stop the actually mechanism from turning (i.e. the rubber but keeps moving round but doesn't move the plastic inside it).
