It didn't work
I normally don't like GC, but bought it for the AE $25 credit.  GC makes you spend more than usual.  In this case, the BK GC didn't even work.  I tried twice, and the BK restaurant couldn't process it.  It does have the balance.  Called BK and requested replacement.<br /><br />Will update this review after getting the replacement.
