I purchased this a couple months ago and it's an okay mouse. I liked my ms gaming mouse better but I've gone thru two of those and had the same problem with both of them (left/right main buttons warp over time)
A major design flaw of this Xornet is the DPI adjustment buttons. They stick up way too high and I'm constantly bumping them. Very annoying when gaming and the mouse arrow suddenly moves very slowly and I have to pause to click the up button to get my pointer speed back to normal. I'm almost tempted to grind those buttons down and out of the way but that would probably void my warranty.
Seriously who designs this stuff? Did they even test this design? If anything, I'd want these buttons recessed as this is something I will never use.
I can't figure out how to disable the buttons. Can't find any software downloads for this mouse either.
Lastly, my left mouse button has lost it's "click" feel. So soft now I can barely tell I've clicked. Causes me to mis-click or double click things by accident.
