Pros: Good build quality, bright backlit keys
Cons: Not fully mechanical, only offers MX red switches, can't access in UEFI or to get into UEFI
On my MSI Z77A-GD55, I can't use the K90 to access the UEFI. My G110 works fine, but the K90 doesn't register anything. So in order to get into my UEFI, I have to go get my G110. That's great... $139 is a hefty price tag, and Corsair's K90 doesn't live up to it.
