Ultraglide Cherry MX Black
All batches in stock and shipping now!
These are the original RNDKBD Ultraglides - Cherry MX Black Hyperglide 5-pin switches (Q1 2022 batches) that have been mechanically broken in for 600k/1.2M/2M actuations. The POM sliding on the nylon simulates years of use, creating a smoother feel just like the vintage switches we all desire - without the dust, desoldering, ultrasonicing, spring swapping, and thrift shopping.
Note that other stores may sell broken in MX Blacks as "Ultraglide". They have no affiliation with RNDKBD and are simply piggy-backing on the name.

205g0 or bust. These linears benefit from a nice thick lube. Give the whole stem a nice light coat, and give the bottom housing sliders a medium coating. I also recommend a spring swap and oiling, as the stock springs are rather heavy, crunchy and overall not so good.
To top it off, some thick films prevent any housing wobble in Cherry switches.
My personal TKL One build uses 205g0 lubed Ultraglides with films and 60g Slow I springs.
I custom designed the machinery for this, and as a mechanical engineer you have my word that these switches are being broken in on precision machines, and not some silly "rock taped to a fan" device. This helps keep the stresses on the leaves to a minimum, as the pressing is no harsher than your fingers. The machine also introduces extremely slight oblique presses, as we never have perfectly centered and straight down presses when we type. This helps to wear the switches evenly and effectively.
Sales on worked in switches are final, as this is a product with a service rendered upon it.
