Great product. Works perfectly with my apple iphone, and 4 ipads. Nice to be able to take photos from my apple products and store to a hard drive. Very fast transfers.

This is an awesome case for the Raspberry Pi. A little difficult to put together based on the minimal instructions. However, once installed it looks great! Very nice high quality case.
