Review: Excellent value and clearly improves my keyboard sound and feel - I recently installed the ThreeBulls 120-pcs Clear Rubber O-Rings on my mechanical keyboard and they’ve made a noticeable difference. The set includes enough rings to dampen all my keycaps, and the transparent design means you don’t lose the look of your world-showing RGB lighting. After installing them, typing feels smoother, quieter, and less “pingy” — the hollow sound under heavy keypresses is significantly reduced, which has been great for shared spaces or when gaming late at night. Installation was straightforward: I popped off each keycap, placed an O-ring around the stem, reinstalled the cap, and moved on. Because the rings are clear and thin, they barely change key travel but just enough to soften the bottom out. I found that my fingers felt less jarred during long typing sessions, and the sound profile shifted from a higher-pitched “klack” to a more muted, refined “thock”. For the price, getting 120 rings is generous and gives you extras in case you decide to adjust or replace later. The build quality held up during multiple days of use — no rings popped out, and none became loose or shifted underneath caps. They also didn’t interfere with the fit or stability of the keycaps. My wrist rest might get more attention than ever because my desk is quieter now. If you're looking for a simple, budget-friendly way to upgrade your mechanical keyboard’s acoustic profile and typing feel without changing switches, this O-ring set is an easy win. For value, performance, and usability, it easily earns five stars in my book.
Review: Awesome: dampen sound easily without sacrificing too much in terms of feel. - I was always kind of skeptical as to how well o-rings could quiet a keyboard. I always thought that even if they did, they would feel weird. But I figured I would give these a try anyway as the loud thwacks on my mechanical keyboard, while satisfying, could be pretty distracting for anyone working near me. I am happy to say that these were pretty easy to install, they definitely dampened the sound by a significant amount, and best of all, they didn't really compromise the feel significantly either. Feel is definitely a bit different, but you definitely get used to it in a hurry. I don't know that I will ever use a mechanical keyboard again with these.

### ⭐⭐⭐⭐ Work with NPKC OEM keycaps and give a stiff landing.
*by K***R on January 17, 2018*

First set LOST. . . . second set took a while to get here. These are the narrower units (0.2mm) so some keycaps will not benefit from them at all as the stems can bottom out before the oring touches the switch housing. I got clear units so they would not obstruct my leds but the keycaps were so gross I replaced them. They do show in older style cherry caps with the clear slits for classic led notifiers so color choice could matter there. These are pretty hard too compared to the 0.4 ones I got from WASD for 15usd years ago. I used NPKC caps and those the stems allow these to cut the clack out without being too mushy. The Blue 0.4 WASD ones would give a squishy landing with these caps. Some other no name ones I got here with a gradient color on them however would bottom out with these and required me to double up the o rings. Really though if you have PBT caps the sound is not as horrible as ABS caps. With ABS these are a MUST have item!
