Rubber Oring Keyboard Switch Dampeners/Sound Reducers Red [40A-L 0.2mm] Reduction (135 pcs w/screen cloth)

I bought these because A) I wanted to try out O rings for the first time B) these were amazon prime shipping and C) there were no reviews. I just recently got into mechanical keyboards and bought a Rantopad MXX with Gateron blue switches. While I love the keyboard, while playing BF4 I started to get complaints on noise volume.These greatly reduce the "clacking" sound of bottoming out (which I kinda liked) but since they're only .2 mm doesn't signifigantly alter the way the switch felt. I was also worried about bottoming out not feeling as "crisp" but I'm happy to say that that's not the case. I'd say, it still feels good, but just, different. Not mushy like a rubber dome, yet not harsh as it was before. I would definitely recommend these to anyone who uses blues as you still get that great audible click without all the racket, or anyone with a mechanical keyboard in general who wants to reduce the noise without significantly altering the feel of their keyboard. A+ product!

Did its job. Do not listen to reviews that talk about how it doesn't quiet blue or green switches. You can't expect an o ring to quiet the loudest switch made. This is designed to keep the key from bottoming out. It does that. Don't put more than 1. This also does nothing. Get a thicker o-ring.Great product and quality.

This product was exactly as described, I had enough to put an o-ring on every key on a corsair k100. This includes putting 3 on large keys like the shift and space bar and had some leftover. I am tempted to get the thicker rings as these still have some travel, but they retain the satisfactory typing we look for in mechanical keyboards.

Put these on my Cherry MX clear switches, or rather put them on the key caps that goes with the switches. For this setup I appreciate the dampening effect on bottoming out. I type very hard and fast, and love the tactile plus audio feed back from mechanical keys, but do not appreciate the unnecessary thunk when the key caps reaches the bottom of travel. These eliminate the issue, and quite possibly reduce stain associated. From now on I put these on all my mechanical keyboards of the Chery MX style stem.

If you're looking to smother the bottoming out sound of a mechanical keyboard, this is what you need. It doesn't silence the sound by any means, but it does make the ringing of the board itself quieter.
