Nice Ergo Keyboard

Been using it for a week now. It takes getting use to with a split keyboard, brown MX Cherry Keys and tilt. The keys are loud per the wife, but i like them. All in all I am very please with the purchase. Plenty of customization and functionality.

Just unboxed today, LOVE IT!

This is such a huge improvement over the Microsoft Natural keyboard I was using.
I got the softest keys available with the out-of-the box keyboard, the Cherry Red, but they are still too stiff and clacky for me so I may swap to a speed silver switch, Kailh or Cherry.
The instruction manual is brief and not very detailed so I've been fumbling a bit with setting backlight colors etc. but I'll figure it out. SO happy to have an improved typing experience, and an aesthetic one too! What a lovely keyboard with all the backlight options.

Great keyboard, especially after some adjustments.

I had been looking for a good ergonomic keyboard for a long time.
As most, I had once started with the Microsoft ergonomic 4000, but to my disappointment (and to that of several other people that I knew with the same board) the quality was lacking and after a few years of use, they were simply broken beyond proper usability.
Then I had the Logitech 350 for a long time and for wireless use, I still keep it handy even now, but it does not quite satisfy completely with the arch of the keys.
2 more keyboards followed, from Adesso and the latest version of the Microsoft ergonomic keyboard (no other model name added, it's just called that now) and the experience on both was just lacking, in terms of how the keys felt.
Then I somehow found this CloudNine C989M, or as it is now called, the ErgoFS!
A full size mechanical keyboard, with all the keys I wanted AND some added macro keys!
The only downside was, I live in Europe, so I would have to import it. I thought about it for a bit, was in doubt about the price and then finally decided to go for it and wouldn't you know my luck? They had a refurb with Cherry Brown switches on sale!
So I ordered that one! It didn't even take that long to arrive and when I opened the box, not only was the standard connection cord in there, there was an extended length one in there as well, that I was very pleased with, as it makes putting the board aside very easy for me. Just pick up the small part, put it to the side of me and then the larger part and shove that underneath the second layer of my desk. Then I can use my cleared desk space for my creative stuff, like drawing, or little DIY projects.
Anyway, the board at first, was still a bit creaky on the numpad side, so after a while I decided to take it apart. Some screws are hidden beneath the rubber pads, so for future tear downs, I have made some holes in the rubber for that.
I stuck some thin foam tape in between the plastic of the housing and the milky plastic that lights up, as that part seemed to be the cause of the creaking. Put it back together and, YAY! Fixed it!
The feel of the keys is great! But, they are a bit noisy. For a long time, I did not do anything about this, but just a few weeks ago, I started looking into ways to make mechanical keyboards more silent on YouTube.
After watching a whole bunch of videos, I first tried adding some foam inside of the housing of this keyboard, as I already knew it was hollow and that it really does cause some echoing!
After that, I was considering taking out the switches, to lube them all individually, but that would require de-soldering, which I was not looking forward to, as it's smelly and time consuming.
So in the end, I first tried this other trick I also learned on YouTube, first trying it out on a less expensive Logitech K835 and then, two days after that was successful, I also tried it on this keyboard.
The trick was to simply use some silicon spray to lube the switches. It's a bit messy, but it's such an easy fix and the sound the keyboard makes now is so much better! Just listen for yourselves here:
https://youtu.be/C6XvN4ODMSg
The few bad thing about those changes, are that the tactile feel is slightly reduced and of course the biggest issue... Why did CloudNine not come up with these solutions themselves? I mean, I get that they can't really lube every switch by hand, but at least they could have tried to make the housing of the keyboard less hollow sounding, right?
Other cons of this product are that the LEDs on the sides are not full RGB, but only have a few modes and that the dial is (in my opinion) too bright and you can't adjust that, aside from the same few settings available for the colors.
Another downside is the software. Though it is functional, I have not seen any update since I bought it in April of 2021. The current software works, don't get me wrong, but not without a bunch of glitches, like saving macros and then the software telling me there was an error in saving the macro, even though it did get saved properly, or the way profiles need to be saved, that is also weird. I don't dare click another profile now, because I am pretty sure the one I am using now, was not saved correctly in the software.
Luckily, the keyboard itself also remembers some setting, so you can disconnect and reconnect it and it will still have the same lighting scheme.
Oh, and then there's the keycap thing. The original keycaps are shiny and a bit unpleasant to touch (somehow too 'smooth', almost like they are slippery), so that's one of the first things I changed out.
I now have most keys replaced by some caps that I ordered from AliExpress. You can see those on the pictures I have used for you YouTube soundtest.
And before I forget, do keep in mind that this keyboard is HUGE! So typing and using your mouse does not go well together. The mouse has to be to the side just a little bit too far.
For gaming though, I can just put the larger portion aside, or even disconnect it! =D

Best keyboard on the market

I love the ergonomic plus the turn nob, and the programmable keys.
