Great cheap but to subdue clacky keys!
Works perfect! I love my keyboard but it was just a bit too loud for my office (I have the Epomaker Galaxy 100 wisteria switches) and I got these to help! I put 3 o rings on my letters since those are most used & put 1-2 on my other keys depending on use. Results came out perfect, subdued but still has the sound of my keyboard that I like. For reference, the :; key I was pressing is a key with no o rings on it, and the L key has 3 on there. It doesn’t change the feel, responsiveness, or speed when I’m typing either. Overall, great, cheap buy!

Excellent Investment - Great for Stacking
These are really nice, especially for the price. It damped the sound and made the keystroke feel significantly better. I stacked mine - 3 to a stem, and I noticed the difference with each ring I added. I ended up not getting enough, and both orders got to me within 1 day. Advice to get them on if you're struggling: open the package and put the rings in the box. Get the needle-nose tweezers (esp. if they curve) and use that to stretch the ring and put it on the stem. The curved tweezers let you push it further down on the stim without ruining them.

Helpful, but more work required for a good board
They make a pretty minimal difference in type sound and feel, but they work as pretty good stoppers to stuff any dampening material into the bottom side of keycaps. After trying out just the o-rings themselves, I ended up poking a hole in little squares of PE foam, poking the stem of keycaps through them, and stoppering them with the orings. This elevates the carcass by a tiny bit, but made my cheap keyboard sound significantly less rattly. Don't expect this to make any change to your board. It takes additional work.

I was glad i went with this brand for the case and the quantity.
These worked surprisingly well for my keyboard as the shift and enter and space all sound really different from my other keys. These worked quite well to quite them down to a much better level to make it less of a distractions for those around me while I'm typing for long periods. Its also wonderful that it came with a case and way more then i needed which means i have spares and can even mod a friends keyboard with them as well.

3 rings is the magic number!
These on their own will not drastically dampen click sound. They change the tone of the reverb. 3 is definitely the magic number (stacking three rings on each key cap stem) to notice a real change in tone. To fully dampen or truly get keys to silence or at least get noticeably more quiet, I highly suggest a change in key switch and possibly (if you can disassemble your keyboard easily) a mat to go inside too. This is my introduction into custom keyboards. I am starting with a cheaper keyboard ($37), $25 set of "silent" switches, a mat, and these rings. I love the visuals and aesthetic but my office is too sound sensitive for clicky keyboards.

Subtle but nice to have difference
These o-rings give the keys that you press a softer touch to them. You are left with the sound and feel of the switch with less of the keycap slam as the switch bottoms out. This leaves the keyboard to feel less vibrationally intense on the fingers, which in turn feel nicer when typing up essays or documents. The sound difference is very minor, but it is audible. The o-rings make it feel more muffled and more like a "thump" than the regular "tock." It's like there is a lower tone to the same bottoming out, and thus ends up being less audible. For the cheap price it offers and ability for you to put it on more than 1 keyboard, or more than 1 o ring per keycap, it's a good nice to have that I would definitely recommend trying out if you sit in front of a keyboard a lot. The features aren't many, but they're subtle and appreciated once you have them. (note they only work on (+) style keycaps. membrane, or logitech's romer-g switches will not work.)

Good quality
Got these to o ring some of my keychron boards. O rings and perfectly sized, and I ran into zero defects, no deformed ones or fused together ones etc. Perfect product.

Doesn't really dampen sound
Didn't dampen the sound on my keyboard, may just be the way the keyboard is built. Good quality for the price tho.

Ce lot de 200 joints toriques en caoutchouc transparent est parfait pour améliorer l'expérience de frappe sur mon clavier mécanique 💥. Les joints sont de très bonne qualité et permettent d'atténuer le bruit des touches tout en offrant une sensation de frappe plus douce et plus agréable 🧘♂️. La boîte de rangement en plastique est pratique pour organiser les joints et éviter de les perdre 🔲. Faciles à installer sur les switches MX, ces joints toriques sont un excellent moyen de personnaliser son clavier tout en réduisant le bruit et en améliorant le confort. Très bon rapport qualité-prix ! 👏

Good to dampen keycaps for sound

If you buy these O-rings to cut down the noise of your Keycaps, thwy do not seem to really work. I fitted them onto my Fnatic Ministreak with Cherry Silent Red switches. Went from fitting 1 to 3 to test the effect. Sound was not really impacted, but with 2 or more o-rings fitted, I started missing keystrokes. Eventually removed all of them.

Perfetti, li ho montati con facilità sulla mia AJAZZ AK820 Pro e hanno risolto il problema del rumore del tasto che sbatteva a fine corsa con quel fastidioso TLACK. Ora il rumore è molto più smooth. I miei colleghi di open space ringraziano.
