Where have you heard that exactly? Corsair is one of the better companies when it comes to return rates. Just because you've owned one bad product from a series with known issues doesn't mean all their products are bad, especially since their PSU department got a new product manager.
well I also bought their RAM which one of two sticks was bad so
not saying they're a bad company with bad products, I've just seen a lot more incidents of their customers receiving defective products, and not to mention when my Corsair Raptor's died on me out of the blue they refused an RMA.
Oh yeah and when I removed pretty much every Corsair product from my comp due to it's crashing/BSOD's everything was fixed. They make good peripherals, but I wouldn't trust their hardware.
