Acekards have a warranty?
It's hidden away in the 'news' section of their site.
QUOTEWe offer one year warranty for real AK2 and AK2i. You can contact your reseller for a replacement for any issue of the real AK2 and AK2i. We do not guaranty any safe use of firmware on fake AK2 and AK2i, and on your DS or DSi. We won't offer one year warranty for fake ones in any case. Please pay attention when you're buying Acekard.
