Summary: Only gave it four stars due to the slow PC transfer speed (~12MB/s). Otherwise it would be a five. I have a Nexus 5 which is not a supported phone according to the Sandisk website. There are a number of non-root OTG apps available on Amazon and other Android stores (most are paid, though) that get around this. My solution is ES File Explorer File Manager which is free and supports this device on a Nexus 5 with zero issues for both playing and copying media.
