Cerulean Tactile Switch by Durock

Product was packaged well, shipped quickly, and are exactly what I was looking for! Super easy to plug and play, and now I have a quiet, tactile feel on all my keys!

CannonKeys sent one of these over with a batch of their 21mm 55g springs, which I didn't actually know what to use in. Ceruleans, at stock, are fine: basically a lighter-feeling Ergo Clear with a more rounded bump, no scratch, and a very lazy return stroke. Acoustically, they come across to me as a bit clacky but full, though not particularly loud. I swapped the stock spring (Gold) for a CannonKeys 55g... wow, what an improvement! Tactility is still well-pronounced without being fatiguing, and the return stroke has a brighter sound now. If you're concerned about all that front-loaded tension, wait for them to get stock of the Medium/18mm springs in your preferred weight for a bit more overall comfort.

I also re-lubed my switch stem with 3204 after cleaning off the factory lube from the stem. Feel free to be aggressive on the stem legs, you won't drop any perceivable tactility and they kinda need it due to typical Durock leaf ping things, though it's not noticeable in-use as far as I can tell. No films needed, the housings fit tight enough.

Overall a pretty good switch stock, responds well to hand-lube, and if you want it to feel a bit more lively, longer

Shipping was fast and Cerulean tactile switches are amazing!

A everything I enjoy about Cherry MX Ergo clears with the cons. These Cerulean switches are great stock and offer a distinct, but refined Ergo clear bump!

Smooth out of the box, rgb friendly w/ transperant blue.
