I went through their warranty process. By then, the Arctic 9 wireless was out of stock and months later it's still out of stock. It's available elsewhere but Steelseries won't refund- they tell me to either wait till they've got it in stock or buy a different one. None of their others have the features I purchased for. They have since ignored my emails for months.
Tip for consumers: Great headset initially but it stopped working within a month.
6 months later, after going through warranty process and being approved, still no replacement or refund.
