tried a few, was good for about a year before it goes kaput but it's affordable, unlike the more expensive brands where it hurts if they break down

which razer mouse you bought spoiled ?
and what is the spolied part ?

hold up on the corsair until you could get the updated M65 or M95 which are obviously better than the previous ones, if it's Gigabyte, just grab any one that you're comfy with as most of them are pretty cheap
