HyperX Alloy FPS's FN key doesn't work properly HD
The top keyboard is the Alloy FPS, the bottom is the Mars RGB. If I press the FN key while already pressing some other key, it will work perfectly with the Mars, but not the Alloy, so if you are playing a game like Apex Legends and running and you decide to change the volume without stopping the running, you can do it on the Mars but not in the Alloy, because the fn key wont work until you release the W key.
