Today I've received my Cooler Master switch tester, which includes a Topre switch. It's been interesting to test Topre. It doesn't differ much from a regular rubber dome keyboard. It's just smoother and with a longer travel. In contrast to MX Red, which feels like a uniform spring from the top to the bottom, Topre has a initial opposition and then it's smooth to the bottom, where you don't feel tor heard the key suddently hitting the bottom, but a kind of slightly soft touch with a deep sound. I like that it feels really smooth. However, it's also slow, as if it is lubricated. The key doesn't go up as fast as MX switches. Despite its long travel, it shares with regular rubber domes the characteristic that it's hard to type softly without bottoming out. I'm not sure but maybe this is not an advantage in terms of comfort nor typing performance. What I don't fully understand is its tactility. If you are forced to bottom out, there's not much use in tactile feedback. As regard weight, this is a 45g switch and I don't find it too light. I'd very much like to try a full keyboard, but for the moment, I prefer to stay with Cherry, especially with MX brown, which is light, comfortable, has a slight tactile feedback which is welcome and doesn't have the irritating click of the blues.
