further testing, i've gone and blown out some more switches using my breath.. some keys regained a lot of clicking ness where as others didn't. mainly okl; hasn't come back but my n,m, p, and i have for example. (i'm a lefty gaming so okl; are using a lot).. Now i'm really intrigued to what's going on.. K it seems that my leats used keys come back to being nearly new when being blown out... so it's go to be wearing right?
