I have done some image research about this controller and it seems they have stolen the design or they had contact with some sellers on AliExpress cause I had seen this design on a controller on that website/app and it seems I am correct. This controller design has been available on AliExpress for years already. Same design, same specifications. I think Anbernic has some explaining to do.
8BitDo and GameSir have a new rival in town when it comes to high-end controllers. Best known for its gaming handhelds, Anbernic has now revealed a new wireless controller with a built-in display, heart rate sensors, programmable rear buttons and even a 1,000 Hz polling rate, even over a 2.4 GHz connection.
