Made from durable EPDM rubber, this 135-piece set includes a microfiber cleaning cloth and installs easily on mechanical keyboards to prevent bottoming out and extend typing comfort. ## Description These Captain O-Ring keyboard switch dampener o-rings can be quickly installed on the stems of your keyboard keys to prevent keys from bottoming out. Bottoming out occurs when a key is pressed down to its limit, causing the key stem to collide with the switch casing. This results in a loud "clacking" noise while typing that affects virtually every mechanical keyboard. Captain O-Rings's keyboard dampeners provide a shock absorber at the bottom of each key to create a consistent, uniform sound while typing. These dampeners also reduce the travel of keys by 0.2mm, which greatly reduces finger fatigue. Durable EPDM rubber o-rings don't crack like black buna o-rings typically do in this application. To install, simply remove each key, place o-ring around the stem, and replace each key. Installation typically takes 4-5 minutes for the entire keyboard and lasts the life of the keyboard. What to expect: This item includes (135) keyboard o-rings and (1) Captain O-Ring screen cleaning cloth in a resealable zip-top poly bag with "Captain O-Ring" branded packaging. Manufactured and warrantied against defect for one year by Captain O-Ring LLC.
