Review on 🌈 FIODIO Membrane Gaming Keyboard with Rainbow RGB Backlight, Ergonomic Standard Design for Desktop PC and Computer - Silver-Black (FK-2028-US) by Travis Varner

After playing with this keyboard for a day, I found that I figured out all the functions of the LEDs, including user input and full protection against ghosting. CUSTOM RECORDING LEDS === If you notice it, FN+ INS cycles through different lighting settings, including one that lights up the arrow keys, WASD, and the ESC key. This is actually the first of 8 different random LED settings that can be accessed by pressing FN + 1 through 8. They have no obvious rhyme or reason, so let's ignore them. Anyone wanting to write custom LEDs will want to use FN+9 and FN+0, which at first glance are empty. Only then will the instructions to press FN + END to start/stop recording actually work. You'll find this works with 3 indicators next to your arrow keys flashing blue during the capture phase. FN + ESC removes your custom LEDs and completely resets the keyboard. They have FN+PRTSC labeled '6-key anti-conflict' - and while that's true, it doesn't give you FULL protection from ghosting. To access it you have to press FN + SCRLK. Also note that FN + ESC resets your anti-ghost to 6. MISC === In addition to these functions, FN + DEL, FN + HOME, FN + PGUP and FN + PGDN activate additional LED settings. The FN+LEFT and FN+RIGHT arrow keys slow down/increase the speed at which the backlight turns on. The arrow keys FN+DOWN and FN+UP adjust the brightness.
