So... the real question is... what's the difference between these PRO 2.0s versus the regular/milky variants? Well, it's straight up a revamped version of the older switches. 
Gateron KS-9 Pro 2.0 Linear switches has less wobble, smoother feeling, and better STOCK sound. They come with an improved transparent housing, and they are for those who are just looking for a good stock switch to use for an AFFORDABLE price. Can't beat this! <meta charset="utf-8">
They all come pre-lubed from factory. They are very light, and can be lubed over.
