Quick Summary

The Owlab London Fog V2 is a medium-light linear built by HMX, pairing a PC top housing with a modified P1 bottom and a modified POM stem. It leans into a deep, rounded sound with just enough clack to keep things lively, and arrives factory-lubed and smooth. If you want a poppy linear that sounds fuller than the usual thin, high-pitched stock options, it’s an easy recommendation.

Specs and Feel

This is a true linear: a clean, uninterrupted downstroke with no tactile bump or click. Actuation sits around 43g with a 49g bottom-out, so it stays light enough for long sessions while giving the keypress a defined floor. Travel is on the shorter side at roughly 1.9mm pre-travel and 3.5mm total, which makes the switch feel a touch snappier and quicker to reset than a full 4mm MX linear.

Smoothness is the headline. The factory lube and the PC/P1 housing combination keep scratch well-suppressed across the stroke, and stem wobble is kept in check enough to feel composed rather than loose. The sound is where it earns its name: deep and rounded on the bottom-out with a slightly clacky top note, richer and fuller than the thin clack you get from many stock linears.

Tuning

There’s little urgency to mod these — they’re lubed and tidy as shipped. If you chase the last few percent, a light stem-rail hand-lube and switch films will tighten wobble and deepen the sound profile further, but treat that as polish rather than a required step.

Verdict

Buy the London Fog V2 if you want a smooth, medium-light linear with a deep, clacky character that doesn’t demand a tuning session before it sounds good. It’s well-suited to anyone building a poppy board on a budget and to linear fans who find typical stock switches too thin. Those who want a heavier press or a longer 4mm throw should look elsewhere, but for everyone else this is a strong, low-effort pick.
