I bought this with Costco Black Friday deal and started using just a couple of days ago.  Today when I was transferring video files from my phone to the card, I wasn't able to because it stopped half way.  Now, nothing can be written on it.It was purchased from Costco, so it's not a fake Microsdhc card.  I tested it out its authenticity with an app on Google Play and verified that it's real too.  Still, it's a piece junk.  What is Sandisk doing to its reputation?I would advise shopper to choose other brands over this.  Surely, it's cheap; but would you rather lose all of the important files that you store in it?
