Corsair or Razer?

go corsair because you don't have to have an account with them to be able to tweak your settings in the software.

I personally have Corsair, but I would say Razer has better software so If the software sticks out to you then go with razer

Razor is way too overrated I'd prefer Corsair over Razor anytime

Corsair is really good stuff but, I'm a Razer Addict since 2 years, but if I remake totally my Setup, I think I buyed Corsair
