I bought this from flipkart so long ago. I’ve been using it from transferring media file from my moo G to this device while traveling. It’s supports OTG for connecting the device through micro usb. For those who travel more and can’t carry any extra storage if the exceed the limit on his phone then this one is very useful tool to save ur day. It can connect on your micro usb port an then need the sandisk app for Android users or else u can use it file manager too. It will show an additional storage just like a computer. Then you are all ready to do ur task
