Broke after only a few months and very little use
on November 18, 2014
The top corner of the card cracked off inside my card reader. That corner must trigger something because the card no longer works (in any of the three card readers that I own). It has only been removed from the laptop a few times to transfer files to another computer and has never been left out so I assume that it had a flaw to begin with. I have had other sd cards for several years without any issues.
