Overall Verdict: 2.5/5 Stars (Mostly “Free” is Limited)

The promise of changing colors for free is true, but only if your specific NOS keyboard model has onboard memory and built-in RGB lighting. If you bought a “Rainbow” keyboard (colors cycle automatically) rather than an “RGB” keyboard (you control colors), you cannot change the color without hardware mods. For true RGB models, the software is usually free, but it is often buggy or requires a hard-to-find download.
