Review on 7KEYS K8 Gaming Keyboard: USB Wired with Premium Big Wrist Rest and Orange LED Backlit, Durable Metal Panel - Ergonomic and Quiet Mechanical Feel for PC Desktop by Mario Collins

It's wired, so there's no battery life, making it odd to have excellent reviews. The LED works well and you can turn it off if you don't want to. Sometimes it doesn't accept my input when I touch the keys. This problem only occurs when using the f1-f9 keys in Mount and Blade Bannerlord (the only game that requires the use of these keys).
