Doesn't change my point. You got burned with defective products in (Maybe) a poor region for their support legals. Too bad, tough shit, it happens.
But subjective data is always subjective. Personal experience is irrelevant. You have no basis on which to claim that manufacturer A is any more likely than manufacturer B to ship defective products or vice versa. You need more data, vastly more data, and the vastly more data that is the internet's common wisdom says that you have a better chance buying Corsair products than just about any others.
FYI - I have one Corsair product, a K70 RGB. It's had to be RMA'd twice (This is my third), on both occasions because of key chattering faults. This third one is beginning to chatter on W. It is not Corsair's fault. The fault is with the switches, which are of course Cherry. Not only is it not their fault, but they've twice given me a turbo RMA (Sending me the product against a credit surcharge for zero downtime), and their customer support is the best I have ever had the pleasure of dealing with (Used to work tech support, contacting Samsung, Sony, Dyson, you name it, I phoned them): They actually pick up the damned phone, in their US offices, and talk to you directly! No Indian call centre!
People need to take a step back and use the perspective to make a real, considered assessment of their situation. Usually, it's not actually the end of the world
