I don't think there is an official policy, but since I contacted Scott before my 30 days was up, I can still return my unit after that 30 day window.

Prior to calling, I too was unaware of any such arrangement. I was actually calling to get my return authorization since I am unhappy with the hiss. I figured if they fixed it for good in a few months, I could always rebuy. Now I get to keep my 950 to enjoy and still have return privileges if an acceptable solution does not come to fruition.
