Thank you for viewing. This is a Bluetooth controller for smartphones. I purchased it used, but the app I was using did not support external controllers, so I am selling it. Image 3 and 4: I confirmed the connection on an Android (Xperia), but since the app was not supported, I could not confirm the operation of each button. Therefore, I am selling it as a junk item. The charging cable and other items besides the main unit are missing. Please understand that this is a used, junk item before purchasing.
