Got the same deal a while back and has been working flawless for me..... Was also worth the few bucks for the 1 year replacement..... Figure close to the end of the year will back it up and get a fresh new replacement one.....
got a class 4 32G on amazon for $22.54. 4G is only $4.50!
I can't post links yet because i guess I am a n00b but you can probably find it by searching. or PM me
