what'd you mine on them? mostly asking to see how hard the cards were actually stressed, i might be interested in one as well 
LBC mostly, as i am a big believer in the coin for a while now, so it's been about all i have mined on any of my cards for like a year haha
I did mine that SIGT coin on them for a few days as well
these cards have 3 year warranties, im sure anything goes wrong they are easily replaced
