With prices of tech items always dropping, getting the bleeding edge stuff usually costs a bit more. Thanks to Amazon and the ability to find deals like this, it was worth while getting the 64GB micro SDXC for my phone. I removed the 32GB I had in there for my Phantom 2 vIsion that had shipped with only a 4 GB unit.  Class 10 is where you want to be when using this for any video recording and you can always count on SanDisk for quality!
