As for the product I have to say that for the price this is what you can find better. I use it with my nexus 7 tablet, and I can plug my joystick PS3 to play many games offered on the Playstore. What impresses me is that it is compatible with all emulators, a very good point in short. (Sixaxis controller allows accounts of all applications on the Store).
I also connected a mouse and it works flawlessly. The picked-USB are recognized, but conditions download an application named "Nexus Media Importer" available on the Playstore to 234. This allows the memory (16gb fills up fast) to no longer be a problem.
I recommend to all Android users and particularly the Nexus 7 users.
