Ok I see it now.
It's funny because on their homepage, it still says 100% guaranteed returns and when you click on it, a lightbox appears, with a summary of the old policy.
When you click on it again, it takes you to the full page, which has the changed policy on it.
Will make for some sticky situations until they fix it
No time limit on refunds if never used.
If the gear fails, full credit.
If used and you just want something else, you get 90 days.
You can't just change out equipment willy nilly though.
Still sounds like a kick ass return policy. 90 days is enough to know whether you are going to keep the shit or not.
