Excellent review, as always. I've just gotten a 3rd NMB keyboard (two RT8255C and an RT101), all three with the "clicky" space invaders.

I'm glad you highlighted some of the quirks of the keyboard. One thing that is especially notable is the gap between actuation and the click, as when you try to type very softly, you can avoid the clicks. This can actually be kind of difficult to avoid errors though since if you type this softly, you'll likely end up with some keys clicking and some not.

Another interesting thing is that you get one click for the downstroke and one for the upstroke. However, there is a point between them at which you will only get the downwards click (if you stop just after it) -- the same goes for the upwards stroke if you stop halfway, but this isn't useful.

You can also remove the clicker piece (the white plastic bit) and end up with effectively linear switches. I made the spacebar and most modifiers linear and it's quite pleasant this way. I also swapped the heavy spacebar spring with the Pause/Break key so that the spacebar isn't so heavy.

The one I just got is brand new. I'm hoping to try lubricating one of them to see how it is.

Cheers mate, glad you liked it :) . I was beginning to wonder if someone here was going to reply to it xD .

Yes, the downstroke distance can influence quite a lot with this thing. I briefly touched upon the things you mention but couldn't put in more about them lest the video became too long - similarly I had to cut some other portions out completely.

The idea of removing the clicker is quite interesting, and I might give it a try, but it's quite a small thing so I'm afraid I might damage it xD . If I do, I'll see how it compares to my 725 though :) .

Nice review.

Only three real problems with space invader switches:

(1) clicky switches actuate before the tactile/click point

(2) the stabilizers are utter crap

(3) they made ludicrously stiff switches for the spacebars

Otherwise, really fabulous switches / keycaps / boards. (Well, except the tactile version; I didn’t enjoy those.) #3 is pretty easy to fix just by swapping the spring between spacebar and some useless key like numlock or something.

It sounds like this board you have might be a bit stiffer than most black space invader boards. The ones I’ve tried are noticeably less stiff than the linear or tactile space invader switches I’ve tried. Would be nice to get some force curves measured, and solid dimensional measurements of the various springs.

Yeah, I swapped my spacebar switch with the Break one. Much better that way! :)

Some force curves would be good for sure. These are definitely very stiff - in fact, that's why the seller got rid of it.

What didn't you like about the tactile ones?
