PEOVER Qty 150 Japan Rubber O-Ring Dampers dampener keycap Key Switches Mechanical Keyboard Cherry MX

I ordered these O-Rings to use on a DasKeyboard Model S for Mac. This keyboard has Cherry MX blue switches. While I love the keyboard and the experience of typing on it, I love my life even more. My happy typing that was causing me to bottom out the keys, and causing loud clacking sounds, was also slowly driving my wife to plot my murder. Since she knows where I sleep, I knew I needed to find a solution.After running some online searches, I discovered you can buy little O-Rings to help dampen the noise that mechanical keyboards make. I saw the WASD line of O-Rings as well as these ones here on Amazon, but the WASD ones were more than double the price for fewer actual O-Rings, and it's not like I'm made of money, you know? Decision made. I ordered these ones.While I waited for them to arrive, my concern continued to grow as I noticed my wife had suddenly taken on a great interest in Amazon's collection of crime thriller movies and had begun furiously scribbling down notes while she watched. Fortunately, thanks to Prime, the O-Rings arrived within two days, before my wife's research was completed.So, first thing, I pulled all the keys off my keyboard. (Note: on this keyboard, the longer keys are held in place not just by the mechanical switch but also by a stabilizer bar. Be careful removing it, or you could permanently damage the little plastic loop the bar hooks to. Search YouTube for the video: "Tutorial: How to remove staibilized keys from a Das Keyboard". Also, I know how to spell "stabilized" - the video title has a typo.)I'll spare you photos of what I found lurking under the keys, but trust me, it wasn't pretty. After cleaning and exorcising everything, it was time to start installing the O-Rings. They slipped on easily, and seemed to be just the perfect size to fit around the posts under each key that connect to the switches. After slipping them on, I started putting the keys back in place, and immediately noticed something strange. Some of the keys were still making a loud clacking sound from bottoming out, but others were indeed no longer making that sound. At first I couldn't figure it out. I popped the loud keys and tried examining the O-Rings on them to see if perhaps the rings were slightly different in thickness. There were slight variations in thickness, but not nearly enough to cause such a big difference in sound. Then I remembered from my earlier online searches having read that you have to be really careful about making sure the O-Rings are pushed all the way down on the post. I got my handy-dandy flathead screwdriver and proceeded to give an extra push to the O-Ring on each key that was still noisy. I reseated those keys, and voila! Problem solved!In the end, the whole process took about 30 minutes, and I would say it has been a resounding success. There's no longer any loud clacking sound from the keys bottoming out when I type. The only sound remaining is the gentle soothing click of the switch activating when the key pushes past the actuation point. The travel distance has been slightly reduced, but after typing about 10 minutes I've already become used to the difference and am actually starting to prefer it. Also, I'm starting to enjoy the slight cushion of the ring when the key bottoms out.Would I recommend these O-Rings? Yes, absolutely! If you have a mechanical keyboard, particularly with blue or brown switches, and you tend to type with a heavy hand, these are outstanding. Do yourself a favor and get them now.Oh, also, my wife seems to have returned to watching romantic comedies, and her notebook has been put away - for now.

These are pretty good. They did three things for me. The helped me to adjust to a mechanical keyboard with more travel than I like by relearning how far to push the key. It isn't efficient to bottom out because you are moving your fingers further than you need to. The click helps but it isn't quite getting past my finger memory. The other benefit is that if you do bottom out it is quite a bit softer which felt better to me. Finally the one other thing this helped me with was keeping the keys aligned. So i have 2 of these mechanical keyboards (Red and blue cherry mx). The blue cherry switch was sticking slightly unless you push the keys strait down which is not easy to do. There is additional friction i beleive do the the alignment of the switch catching the metal piece they use to generate the click feedback. Because the keys aren't going quite as far in the switch this appeared to prevent that resistance. I didn't really have that particular problem with the red however, but it did improve the reds on the first two measures.Anyway my overall impression was that these are great. About my experience in general after having used these and mechanical keyboardsl: I do still feel like blue switches have too much resistance. I'd prefer shorter travel and way less force to push they key, and "learn to use" the minimum force to type. I am a software engineer and a very fast typist. I also wish they'd make these keyboards in ergonomical configurations, like the ms natural. Regardless these did help with a number of problems. For me this was less about noise, I noticed some change there, but i don't really slam down my keys, that is something i have already tried to avoid doing, and have learned good habits there. while these may reduce the impact slightly if you are causing that kind of force on the keyboard and you type a lot it is not likely to be very good for your hands even with these i'd try to avoid that, but it may help.I summarized my experience here so that you can compare with whatever problems you may want to solve. If they intersect I hope this is helpful.

I used these on my Leopold keyboard with Cherry MX Brown switches. When I slide them the whole way up into the keycap, they help mute some of the clatter from bottoming out the keys. If you don't slide them the whole way up, they may reduce key travel by a little bit.These are medium density, I'd say, so they aren't particularly springy, but do blunt the impact when the keycap bottoms out. If you don't typically type where the keys bottom out, you may not notice much difference in them. They probably will make a bigger difference in MX Blues than they did in my MX Browns.For putting these in, I recommend a wire keycap puller ($3-8 in most cases), and I found that I could use the barrel of a pen to help slide the rings up into the keycap and snug them at the top. That made it a little faster for working through all the keys.If you want a slightly harder O-ring that is a very tiny bit larger diameter (and thus does slightly change the key travel), I found these worked: http://www.amazon.com/gp/product/B000FMWLR8 and were rather cheap.I used these softer ones in this listing for all the letter, number, and cursor keys (the one I'm likely to type/click repeatedly) and then those other harder ones for the function keys and extraneous keys that are usually only clicked individually, and far more seldom. This way I will have enough rings to do both my Cherry MX keyboards with the 150 included in this set.Overall I am satisfied with the purchase and would do it again on my next keyboard, although there are some softer O-rings out there (40-50A) that I am curious how they would compare. But no regrets on this purchase.

Good, It has not taken away the mechanical experience but sound could have been muted more.
