The memory card itself is great but the Ellipsis 7 doesn't have the ability to store any apps without first "rooting" your device and installing other [free] software.  The problem is, it's incredibly difficult to setup and you have to be a computer expert to understand what needs to be done.  If you have an Ellipsis 7 and you want to expand it's memory, don't get this until you've reviewed all of the steps online and fully understand what you need to do.  (If you know LINUX, this should be easy for you, otherwise, be cautious on this purchase.)
