8bitdo Ultimate MG Bluetooth Game Controller This is a Bluetooth game controller from 8bitdo for mobile devices. I purchased it in September of this year, but I am selling it because it didn't suit my needs. I only used it for about an hour when I bought it, so I believe the condition is good, including the battery. The sheet that holds the mobile device is made of a rubber-like material, so it has become slightly whitish due to its nature. Therefore, please refrain from purchasing if you are looking for a product in new condition.
