Yeah I had problems with my warranty and was hopping on here to check if lubing would void my k95. Sent mine in after having a completely dead light after ~3 months (looked dim after a week but was busy with school) and my replacement came with a good 6 keys already "pre-pulled" off the keyboard. This one definitely feels less responsive than my other K95 like it didn't get factory lubed and I definitely don't feel like going through another warranty process right now especially when I need my keyboard for school (even with the advanced RMA) looking @you Corsair on that one.
