After finally not, buy a left-handed mouse (Razer Naga)
I discovered that I was a fake left ... well I do not reverse my buttons ...
... The result ... is naga "caca" for me! Uncomfortable as possible.
So I returned to this wonderful mouse (under Ok button)!
Jai fear what will do as lIntellimouse Optical (exorbitant prices now) that jen took several in stock!
In my first 3 years is still not HS.
