Vortez reviewed the SteelSeries Apex 9 Mini
A quote from the article:
The Apex 9 Mini comes equipped with their new OptiPoint Optical Switches, which offer a 33% faster actuation than "the competition", with an optional 1mm or 1.5mm actuation distance, these new switches can also be removed and swapped, giving the keyboard extra customisation options and longevity that other mainstream keyboards can't compete with.SteelSeries Apex 9 Mini Review
