I bought this adapter for transferring presentations from my iPhone 5. The cable I close here to a so-called pico projector. The presentations run on Google Drive or the 'Slides app'. Both work fine and as expected. The projected image will change its position during the rotation of the iPhone. Sound is also transmitted. YouTube is working properly. Otherwise, the iPhone screen is transmitted virtually. The quality is very good. Even though it's a steep price for such a small adapter, it fulfills its purpose in my opinion. Highly Recommended!
