However, Corsair tested their keyboards further and realized that the white infill material used on the laser-etched keys was defecive.
They have changed the formula and a new production run is underway.
They have sent me a free shipping label so I can send mine in to get a new replacement K60.
Interestingly, they first offered me a free upgrade to a K90 backlit model with the additional macro keys - but I declined because I prefer the narrow K60 and already came up with a lighting solution of my own.
I simply put an Antec Halo 6 LED USB-powered strip under the leading edge of my monitor stand and it casts a soft glow over my desktop area without causing any glare on my screen.
There is one other issue with the K60 - myself and some other users have had a phantom "stuck key" phenomenon occasionally occur.
It usually happens in driving games - one of the keys will seem to be stuck, making the vehicle steer consistently in a circle even though the key isn't physically stuck. I usually have to Ctrl/Alt/Del to exit the game to fix it.
It has also happened during a forum post or two - I was editing a word at the end of a long post and the backspace key stuck and erased the entire text, very frustrating!
I must stress, however, that this sort of thing is rare - only a handful of times in 4 months.
Corsair is also aware of this issue and has come up with a fix that they are testing internally before releasing it - possibly as a small program that runs in the background.
All in all, I consider these issues as teething problems that occur when a company starts releasing new products in a field that they had no previous experience with.
I trust Corsair will fix them and I will end up very happy with my K60 - which I really like otherwise.
