Comments on Keygeek M3 switches | Comments on HMX Lunar Stone switches |
M3 is the first Keygeek switch that uses the LY material. LY itself is not an actual raw material but a made-up code name for certain material blends. In Keygeek's case, LY stands for a blend of POM. Paired with the P5 bottom housing, which is also super rigid, the M3 switch has a clacky and even metallic sound profile – Unikeys. The Keygeek M3 are MX‑style linear switches and the first model in the series to use an LY stem – a special POM blend that creates a bright, clacky sound profile. Combined with the very firm P5 bottom housing, the result is a switch that stands out clearly from the softer, more “creamy” Keygeek variants and offers a crisp, resonant typing feel – MonacoKeys. | The HMX Lunar Stone linear switches are manufactured using HMX's brand-new full POM housing mold. It is the first full POM HMX switch. As the first full POM HMX switch, we expected it to sound and feel a bit different from other HMX switches in the market. They have proven to be quite unique; They sound fuller and thockier than most HMX switches yet still come with the bassy bottom-out sound. The travel feels very smooth yet there is audible scratch since that's what most people love about full POM switches – Unikeys. |
