Article fits the description and works great - I tried with Nexus 5, 2013 and Nexus 7 with Moto G, all files are readable (PDF, mp3, mp4, flv, jpeg). The key is perfect for all smartphones and tablets all compatible micro USB host. You just need to install an application of the kind OTG Disk Explorer Lite that will handle playback or transfer. I am happy with the product and fast delivery.
