I swear everything I have from Corsair with an LED has burnt out LED's.... My K95 has several burnt LED's, now my M65's LED just burn out too! It really is sad because they are using this as a large part of their marketing now... The K95 RGB...

I already sent back two K70 keyboards for LED problems. They were so backed up with RMA complaints that I was upgraded to a K70 Gunmetal grey with Brown switches. This has been fine until last night when I noticed one of my LEDs is dimmer than the rest. I'm afraid to RMA this right now because I don't want a flood of LEDs going bad all at once like everyone else.

The devices work great otherwise. My k95 is my favorite keyboard to date and I like the m65  as well. Just that their LED's are junk... Which amazes me... Because, they are LED... LED's are supposed to be long lasting... 

I have never had a nicer keyboard. Every time I say it's working fine it starts typing double characters so I'd better complain about something this time. A dim LED indicates a cheap product and that annoys me having to pay over $100 USD for a keyboard that should last a lifetime. I was convinced that the LED problem where they totally go dark was from a cold solder issue during manufacture. I might decide to RMA after the Christmas rush. I'm just nervous about the quality of what I'll get in return. I'll have to think about whether I can live with a dim 'R' key for now. If you didn't know it was like that you'd probably never notice.
