These are very quiet switches. There is only a soft murmur as the stem descends through the housing. There is no sound on the bottoming out, unless you really slam your fingers into the keys. The stems have a unique design eliminating any need for silicon dampeners, but it creates the tiniest vibration when the stem nears the bottom out. Only the most sensitive typers could notice it; it's not anything close to a tactile bump. I don't feel that in the course of normal typing. Since there aren't any dampeners, the switches don't feel gummy or murky. I am satisfied with the factory lubing; I haven't noticed any scratchiness with my sets of switches.
I prefer silent linears, and I doubt that I will try anything else. The low cost of these Haimus is icing on the cake. If I get another keyboard, I will purchase more of these.
