Thank God for amazon return policy or I would be incensed.  This little platic device from hell died unexpectedly after 37 days.  I lost all my phone pictures that were not stored on the phone.  I lost the music but have most on PC.  I lost the videos I had from concerts.What happened was the phone gave me a warning that the storage device (Sandisk Ultra) could not be found.  I took it out and restarted my Galaxy Note 2 and it worked.  then about one hour later I got the same warning.  I tried to save my data with MY Backup Pro App (I had to purchase an extra 3 GBs of data for cloud because the App comes with only 75 MB or something like that and so I backed up everything on the Sandisk Storage).  And as it was backing everything on line  using the Backup Pro Cloud, the Sandisk fried and stopped the backup process.  I was prompted to format the storage disc but everytime I performed this process, the phone would not complete the format.  Now keep in mind that I was not near a computer because I was on vacation so I could not use a computer to format in Fat32.I am returning this disc and purchasing a Samsung 32 GB that costs over 50 bucks.  You get what you pay for.
