Nowhere says it requires a wireless controller. We have a wireless controller at our house that we've been trying to set up this thing with and it's bullshit. That does not work. We'll send it back.
Pros
Power input connector: If you use a keyboard with a lot of RGB backlight decorations, this product may not work normally due to insufficient power supply. At this time, you need to connect a 5V DC adapter to this product.
