Made from durable EPDM rubber, these dampeners minimize finger fatigue and are designed to fit a variety of mechanical switches, making them an essential upgrade for any keyboard enthusiast. ## Description "Bottoming out" is a term used to describe when a keystroke is pressed all the way down where the stem of the switch hits the inside of the switch casing. This causes a "clack" from the collision on mechanical keyboards. Switch sound dampeners are soft rubber O-rings that can be installed onto every single keycap stem to cushion the landing of the switch by stopping the keystroke just short of the point of bottoming out. This also very slightly reduces the max travel distance of the switch. (0.2-0.4mm of 4mm total travel distance. Varies by O-ring type.) This modification is popular among mechanical keyboard owners from around the world. Since most people will bottom out at least a fraction of their keystrokes, the switch sound dampeners will cut away extra noise giving your mechanical keyboard a consistent sound output while typing. The added shock absorption can also help with finger fatigue during long typing sessions. Made of industrial grade EPDM rubber which has much better resistance to cracking and tearing than nitrile or silicone rubber. Fits firmly onto the stem of your Cherry MX keycap. Installation will require removal of your keycaps. Install O-ring on the stem of the keycap. Install the key and press down firmly to fully seat the O-ring. The O-rings are designed for our keycaps and keycaps from many other popular brands with Cherry MX Swtiches. Please note that some keycaps, such as the ones found on Cherry Corp keyboards have different stem lengths and will not work properly with our O-rings. ## Features - (Blue) 0.4mm travel reduction.

Faster typing. Great sound. *by B***. on Reviewed in Canada on 20 April 2021* I wasn't sure that the thickness of these dampers (the thickest).At first, I thought I made a mistake about the thickness but when I got used to it, I noticed that I was typing a lot faster than before. In fact, I noticed that the others were typing a lot slower than me. And the sound of the mechanical keyboard is wonderful, no more hammering sound of plastic over plastic when the keys hit the bottom of the mechanism. Just the mechanical click sound from my DasKeyboard Cherry blue keys. Delightful sound and very good physical feeling! It's like hoovering over the keys.For aficionados. ### ⭐⭐⭐⭐⭐ Changes the feel of the keyboard for the better *by T***R on Reviewed in the United States on 7 July 2015* I bought these to install in a CM Quickfire Rapid keyboard with Cherry MX Red switches, and am very pleased with the new feel. Previously bottoming out each key resulted in a loud plastic "whap" noise, but with these rings it's more of a solid "thud" that feels much better. There is no interference with travel other than at the very bottom. Overall the keyboard is -much- quieter. The o-rings seem very durable. It's just a wee bit tedious to install them all, but overall it's not too time-consuming (note: you can't do it without a keycap puller tool). The only tricky part might be the stabilizer supported keys like control, return, and the spacebar, if you haven't done it before. The WASD keyboard folks have a helpful video on their site, under Support->Tutorial->Removing Cherry MX Keycaps, which shows how to remove and reinstall keycaps with stabilizers. The price of this little baggie of tiny blue washers is a bit steep, but they definitely provide a noticeable and qualitative improvement when you type. Comparing these to the red o-rings, which are half the thickness, I would speculate that the red dampeners would convert the "whap" to a "thud" but with a much less cushion-y feel, and you would not notice them as much when you bottomed out. I'm glad I got these, as it makes the keyboard feel more solid, somehow. ### ⭐⭐⭐⭐⭐ There seems like a significant difference in how quickly the key hit ... *by D***E on Reviewed in the United States on 2 July 2017* I received and installed my dampeners today. Not nearly as hard to install as some indicated in other reviews. They make a significant difference in sound but that also results in a difference in feel. There seems like a significant difference in how quickly the key hit bottom and initially is enough that some characters are not being entered despite a click from the switch. This results in what my wife calls angry typing where I smash the heck out of every key. I am currently attributing this to the fact that they are new and I am ust getting used to them/wearing them in.Am giving a 4 star for now and will increase to 5 later if the missing character thing improves.Update: I have had these on for about a month, maybe longer, and I am very pleased. The missing character thing stopped as I kind of expected it would, and I have really grown to like the shorter key travel. Increased to 5 stars.Edit2:I have had the dampeners on for several months now and they at this point have felt exactly the same after initial wear in period. They continue to not only improve the sound of using my keyboard, they also improve performance from a keyboard I was already more than happy with in the reduced travel path. Do it.
