Review on ThreeBulls 120Pcs Rubber O-Ring Switch Dampeners Keycap Red For Cherry MX Key Switch Keyboards Dampers by Garry Ortiz

I bought these o-rings, a WASD "sampler" keyboard switch (which comes with about 6 red WASD equivalent o-rings) and a pack blue WASD o-rings that are about twice as thick. I compared these three to Cherry MX Brown switches on my Ducky keyboard and found that I clearly prefer the ThreeBulls. They produced springy but quiet key travel and didn't shorten switch travel too much, which seems to bother me. All of this means that the only thing wrong with this brand and this particular product is that the amazing price implies less than amazing performance. It's not relevant. Those o-rings are awesome.
