I'm putting these on a Logitech G512SE with the Clicky switches - similar to Cherry MX Blues, and note that it's important to get clear o-rings if you have illuminated keys because the o-ring does overlap with the key letter/number cutouts on this specific keyboard. While they don't block the key light, you can see a faint outline and different transparency of the o-ring through the letter cutouts.While the out-of-the-box typing experience was fine, adding these o-rings significantly dampened the clack sound of the key plastic bottoming out on the switch housing, to the point where I can only hear the sound of the switch being actuated rather than the combination of both the switch click and the key bottoming out (with the larger keys being the exception). Instead of the usual hollow bouncing of plastic, I now only hear the much quieter click of the key switch on the small keys. It still dampens the large keys (space bar, shift, enter etc.) but it's not as dramatic of a sound difference compared to the small letter keys. Just on the sound dampening front, the o-rings do the job well and are a winner.As noted by another reviewer, due to their thickness (which is about 1.8mm thick) they have roughly halved key travel. If you like your key travel distance, I would stay away from these and find o-rings with a smaller profile. But for me, I've always had an issue with the key travel being too deep so these were perfect. Because of shorter travel, I can really capitalize on the short actuation distance (distance for key press to register), making typing a lot easier, faster, and smoother. On top of all that, the o-rings have fully stabilized the keys whereas before, some of the keys could be tilted or wiggled about depending on the angle the press was coming from and they tended to be very bouncy which also has been completely negated by the o-rings.Overall, these o-rings were the perfect thickness to both noticeably quiet down overall typing noise and allow for adequate key travel on my specific keyboard. They also completely stabilized the keys resulting in a much more satisfying, solid, and smoother typing experience. These are a very affordable and necessary mod for any mechanical keyboard.  Read Less
