hey RiO, i beg to differ with you on this basis.
my copperhead has become > 1yr old and I hadnt had one lingering issue with it.
Whatever issues were there (incompatibility with NF4 chipset), were fixed early along using firmwares.
You cant compare the accuracy afforded by the Copperhead by anything else in the market.
But then again, it is pricey as well.
4k or so.
For 3k, a G7 or a MX518 seems about perfect.
Go ahead with either Nishant, you would be surprised how much you can benefit from such a simple upgrade as a mouse. I am scared to face your rocket launcher now... seriously.
Regards,
Karan
