I received it yesterday.
My impressions:
Browns
- I'd already pre-ordered a Leopold w/browns from EK, so I assumed I'd like the browns, and I do. They're simple, smooth, light, and the tactile bump tells you when the switch is activated. The tactile bump is not nearly as precise as buckling springs, but it feels exactly like what it is - running a piece of metal over a soft plastic ridge. I'd like something sharper and more pronounced, but this is still very good.
Reds
- I've been curious about reds, and I like them a lot. I'm a fan of bottoming out, and that's pretty much all there is to these. I can't decide whether I like them better than browns, but they feel...sexy. Now that I've tried reds, I'm sold. I'll definitely be getting a board with them.
Blues
- I really like the click and feel of these at low typing speeds. They feel and sound just about as good as buckling springs. The tactile bump still feels imprecise, much like the browns, but the click is sharp and gives the illusion that the tactile bump is equally sharp. At high typing speeds, though, they lose their appeal for me. The clicks and bumps blur together, and the whole experience is a bit indistinct. They also feel a little bit sloppy to me. Maybe that's due to the white slider moving up and down inside the switch, but I can't be sure. In any case, for a clicky switch I much prefer buckling springs at high speed. I was planning to get a board with blues at some point, but I may just pass.
Blacks
- These are a mixed bag. They're a lot like the reds, but too much work. Still sexy, but not for me.
Clears
- I already have a board full of these, and I know I don't like them. The tactile bump is fairly close to the browns. They feel fine at low speeds when pressing lightly, because I can really feel the tactile bump. At high speeds they feel good if I press hard enough to bottom out, but I can't feel the tactile bump. I normally type fast, and I don't like the extra effort. With these, high speed + low-effort = springy mush.
I also noticed that the larger keys (+, Enter, and 0), which are all blues, feel and sound a bit different from the other blues. It seems like the bottoming-out is dampened, with a softer feel and very little clack sound. I assume this is the result of Cherry stabilizers.
I'll send this out in the next couple of days. Thanks again, SirClickAlot! Being able to try these switches is immensely helpful.
