Purchased to support Gameboy Zero build. I tried other much cheaper alternatives from eBay but these devices couldn't support multiple devices interacting with the Raspberry Pi. It was with great concern that I spent $13 on the Targus device. It works perfectly. In a build I use it to connect an Arduino based gamepad, USB audio and an external USB port. The second build uses two gamepads and USB audio. So despite the high cost, it works great.
