I've been enjoying my games using an XBox 360 controller. I've had OTG on other phones, but haven't been able to use the controller without a powered USB hub. This device has a big enough battery to power the controller on its own! So much fun!
I'm not using it with games but I am using it as an ext SD card for music and such. Especially while at work I download so much on my phone then transfer it to a flash drive then use the otg cable and flash drive and plug into my Nexus 7 that's installed in my truck dash as the head unit video player navi. Works great.
