Picked this up on sale.. doesn't work, only shows up as a 1MB (yes, Megabyte) card that I can'd do anything with.  I already threw away the original packaging too.  I'm sure returning it is going to be a huge PITA because of that.UPDATE: After writing this (albeit, short) review I found this is not uncommon.  I also found that this card was deliberately crippled despite the product description saying "The SanDisk Ultra microSDXC UHS-I Card works with any microSDXC compatible device."  That was all the motivation I needed to process a return on it rather than having it replaced.
