I have been using a similar type of switches from a4tek for a long time. On the old keyboard, they never failed in 4 years. Specially took on red switches (which do not click). If you do not hammer hard, then the sound turns out to be slightly louder than the membrane (the plastic of the keycap against the plastic of the switch base). All the shortcomings that I have described are eliminated in the next generation. I tried both, the new model is cooler, but not much, and they don’t carry quiet switches to us.
