BSUN Jade Rosales 45g

Quick Summary

The BSUN Jade Rosales 45g is a light, factory-lubed linear built around a milky PC housing and a Y3X stem. It leans into a creamy, rounded sound and a glide that’s already smooth out of the bag. That makes it an easy pick for anyone who wants a low-effort linear without a tuning session. If you like light switches that feel deep and soft rather than clacky and sharp, this is a comfortable pick.

Specs and Feel

This is a true linear with no bump or click: just a clean, uninterrupted downstroke. Actuation lands around 45g with a 53g bottom-out, so the press stays light from top to floor and never feels fatiguing during long sessions. Travel is slightly shorter than MX-standard, with roughly 2.0mm of pre-travel and 3.5mm of total travel, which gives the keypress a marginally snappier, more responsive feel than a full 4.0mm switch.

Smoothness is the standout. The factory lube is applied well enough that scratch is hard to find, and the stroke reads as creamy rather than glassy. Stem wobble is well controlled in both directions, with only minor play that won’t bother most typists. The modified PC top and custom milky bottom housing combine for a softer, fuller acoustic than a typical PC linear, more rounded thock than high pitched clack.

Tuning

There’s little obligation here since the switch arrives pre-lubed and smooth. If you want to refine it, a light pass of switch films will tighten the already-modest housing wobble, and a careful re-lube can deepen the creamy character further. For most builds, dropping these in stock is perfectly reasonable.

Verdict

Pick it up if you want a light, smooth linear with a soft, creamy sound and don’t want to spend an evening tuning. It’s an especially good match for fast typists and gamers who prefer minimal finger effort. Heavy-switch fans and anyone chasing a sharp, marble-y clack should look elsewhere, but as an accessible everyday linear the Jade Rosales 45g delivers.
