Quick Summary
HMX Poro is a smooth, full-nylon linear sold in two weights: a light 37g and a medium 45g. The all-nylon housing gives it a fuller, slightly deeper voice than HMX’s brighter PC-topped switches, and the LY stem keeps the travel clean. If you want a smooth linear that leans toward a warm, fuller sound rather than sharp clack, Poro is an easy and inexpensive choice.
Specs and Feel
Poro runs 2.0mm of pre-travel into a 3.7mm total stroke on a 22mm single-stage spring. The 37g variant bottoms out at 42g for a fast, featherlight press, while the 45g version bottoms out at 50g and feels more grounded. The LY stem in a Nylon P3 top and Nylon PA30 bottom housing is the defining choice here: full-nylon housings absorb the high frequencies, so Poro sounds fuller and a touch deeper than typical HMX linears, landing in medium-thocky territory rather than bright clack. Factory lube is applied well, travel is smooth with minimal scratch, and wobble is low. It is a clean, well-rounded linear.
Tuning
Poro is good stock and needs nothing to be enjoyable. The factory lube is even and the nylon housing already does the sound-shaping work. If you want to push the fuller sound further, a heavier 205g0 on the rails will deepen it slightly, and a spring bag removes any faint ping. With the lighter 37g version, keep any relube minimal so you do not add drag to the low spring weight. Films are optional given the tight nylon housing fit.
Verdict
Buy Poro if you want a smooth, fuller-sounding linear at a low price and like the idea of choosing your weight. The 37g suits gaming and light typing; the 45g is the safe all-rounder. If you prefer a brighter, clackier signature, HMX Macchiato V2 or Lanikai go that way; for a similar light-weight choice with a thinner sound, HMX Moonlit Bleu is the alternative. Poro is the warm, easy option.
Frequently asked
Which Poro weight should I choose?
The 37g (42g bottom-out) is light and fast; the 45g (50g bottom-out) is a more planted all-rounder. Pick by how heavy your typing is.
Why does Poro sound fuller than other HMX linears?
It uses nylon for both the top and bottom housing. Full-nylon housings damp the bright top notes and give a deeper, fuller sound than the usual PC-topped HMX switches.
Is it smooth stock?
Yes. The LY stem and factory lube make for a smooth glide right out of the box, so no tuning is required.
