Two edges. One used as pen drive. Another is OTG. Edge of the OTG is very tiny. So it break easily. If we handled with care, after using several days its not working due to pluging and getting out for multiple times. I'm simply telling - If you're not using it regularly then buy this.

I brought this product with an eager and lately I was really disappointed. I received the product good as it is. But its transferring speed with my laptop was too slow. It takes a bit longer to transfer files. And after few days the OTG got broken inside and its not working now.
