What is the opinion of Reddit about the
Corsair Vengeance K70 Mechanical Gaming Keyboard – Cherry MX Brown (CH-9000050-NA)?

That link is for the mx Red/Red led. If you actually read through the corsair forum thread or the even the amazon reviews for the Brown/blue led you would see that many people have had led issues. Even people giving it 4-5 stars are reporting dead keys. I per-ordered mine over the summer and received it on Sept 13th. By Thanksgiving I had 6 dead lights. I got an RMA replacement around xmas and now have 28 dead lights ~5 months later. I expect it to look like North Korea by winter.

Edit:typo

Best looking mech keyboard I’ve seen, releases next week
