Captain O-Ring - Rubber Oring Keyboard Switch Dampeners Blue [40A-R 0.4mm Reduction] (135 pcs w/Screen Cloth)

I have a CoolerMaster QuickFire XT (blue switches) and reckoned my keys were a little bit noisy considering my housemates were awoken when I started my homework in the morning. I decided to go with these O-rings as I quite like the chiclet keyboards on some laptops and feel like I can type very fast with them, so these "fat" rings (as opposed to the red "thin" rings) should do the trick.Installation was simple, albeit a bit tedious. I don't have a keycap puller so I fashioned one from a paper clip. (You should do the same instead of paying $6.99.) I initially only installed the O-rings on the 26 "letter" keys because I wasn't sure if I'd like them or not. Of course, as soon as I hit the space or wanted a capital letter the difference (in noise and feel) was massive, so I ended up putting the o-rings on all the "main" keys too (shift, enter, backspace, alt, etc.).I quite like the difference. It is noticeably quieter, although most definitely not silent. I would say the sound level is reduced 30%. But the biggest difference is the feel, as the travel is much shorter and the keys "bounce back" at the bottom of the stroke - as a result, my typing speed went up about 12 wpm. Overall, would recommend especially if you are wanting a change in the feel as well as the sound, but if your intention is only to reduce noise, these may not be the best solution. Still, a good thing to try before buying a new keyboard with different switches, however.

These O-rings saved my keyboard from getting trashed. They made my keyboard a bit quieter and softer to type on. However, they didn't dampen the sound as much as I hoped, and they changed the feel of the keys slightly. They are also a bit pricey.

I am pretty happy with the results of these on my MX Brown keyboards. There were actually enough rings in one package to do my whole Tenkeyless board, as well as most of another Tenkeyless board, but I'm buying another pack to finish that one off as well as put them on my Vortex POK3R 60% board.As others have said, this doesn't completely silence the keys, but it probably does cut down on the noise by about 30%, and adds a different, more pleasant (to me) tone that's less 'clack' and more 'thunk'.When I showed a co-worker (who sometimes complains about how loud my keyboard is) the difference on the keyboard I wasn't able to fully outfit, she agreed that it was quieter, and wasn't able to hear my typing nearly as much from across the room.It does change the feel of typing a little, as there is a little bit of dampening at the end of the keystroke, but I also don't mind that, and in a way it almost makes the keystroke feel more solid to me. I'm also not having issues getting used to any shorter activation, either in gaming or typing.In any case, I am pretty happy with these things and ordered a second set, as I mentioned before. I also like that they included a cleaning cloth, just because it's nice to have them.

Worked to silence my keyboard. Much quiet. Advanced 360.

I got these, along with some red o-rings, to try to dampen the noise of my Keychron K2 Pro with red switches a bit.I ended up preferring the red rings, as these blue ones changed the feel of the keys a little too much. They do dampen the noise, which is appreciated - just not quite as much as I'd hoped.I'm not going to dock anything for preferring the red rings - I got both knowing I'd only pick one or the other in the end. But I'm giving 3 stars mostly for the value: The effect the rings have on feel and sound is so slight and the price is so high compared to what they must cost to produce that it's a pretty bad value.

These pretty much completely dampen the sound of the downstroke on my keyboard as I am no longer bottoming out. I'm a pretty light typist though, so if you are forceful when you type, there might still be an audible sound on the downstroke. Note that these will not do anything to help with the sound of the upstroke. If that is bothering you, your switches (and possibly the way you type) are the culprit, not these orings.I recommend!

These are really nice and do the job well. You do have to give them a bit of a stretch before applying them to your keycaps. They are nice and cushiony making for a nicer key press. They are American made and I love that. I had only one issue. They are packaged in a small ziploc baggy with the free cloth and in order to get to them you have to either pull them out from around the cloth or try to pull the cloth out without all of the little rubber rings going flying. There has to be a packaging solution that can alleviate this issue. I hope they find it soon before I need to mod my next keyboard.

I bought this back in 2018 and threw it out in 2022.They were great while they lasted! Defiantly cut down on the noise that my keyboard was making super effectively. They kinda wore out and got a little bit sticky at bottom out, so I just tossed them. Good product over all
