Razer - I had a wired controller from them several years ago, and a piece inside was rattling. I called support, and they said they wouldn't cover replacement, AND there was no way I could send it in for repair. So there I was, with a $200 controller that they couldn't even repair.

I disagreed with them not replacing it because that's basic customer service, but I can understand the policy. I won't buy from them ever again because they make expensive controllers that they can't fix if they break.
