Comments on Keygeek Mirror Lake V2 switches | Comments on HMX x 80 Retros FJ400 switches |
Do they remind you of a peaceful ice lake? The Keygeek Mirror Lake V2 switch is a full upgrade from the V1. The major improvement is that they are now manufactured using Keygeek's newest mold set, which fixes some of the issues that existed on the V1, such as stem wobble, loud but noisy bottom-out sound, etc. The UPE stem plus PBT+%30 FG bottom housing creates a loud, clacky, and clean sound profile. The UPE stem also buffers the bottom-out feel to make it more comfortable to type with. Just as we always say, don't expect Keygeek's flat tip UPE stems to sound deep or thocky. They are more like Keygeek's LY blend for clacky switches – Unikeys. | The switch color scheme is inspired by the Fuji 400 film roll. Compared to traditional HMX clicky switches, this switch has a more thocky sound. It features an HMX T2 material stem, P2 material bottom housing, and a PC material top housing that dampens the sound. With a total travel of 3.8mm, the sound is quieter compared to the 3.5mm travel switches – Deskhero. |
