This is the second one of these chips that I received.  The first either had a latent physical defect or damage in transit, but it snapped in half on first use.  I was really bummed, but determined to try again.  This was a breeze!  The chip blazes, doubled the capacity of the 32 GB chip it replaced in my ASUS TF700T tablet, and holds ALL of my music and documents with plenty of room left over!  I now have 128 GB available on my tablet, and it all works flawlessly.Anyone that is looking to upgrade needs to do a little due diligence in determining that your device is able to address 64 GB's, but with that reservation, I strongly recommend this little gem!!
