This has been one of the best accessories I have bought for my spark. Transfering all the photos and video over wifi was taking WAY too much time. With this, I can pull the micro sd out, put it in the adaptor and then plug it into either USB, Micro USB, Lightning, or USB C. Works great on my iPhone and iPad mini 4.

I wish I had seen this one before I bought the Lexar. The lexar feels CHEAP. I don't think it will last long.
