This has been a fantastic improvement in ergonomics in my daily development workflow. Do yourself a favor and buy one of these, you will not regret it. It may have a steep learning curve, but the rewards ultimately make it all worthwhile.

I completed building Span, and I’m thrilled with how it turned out. For this build, I used Kailh Choc V1 Red switches, and ChocFox CFX WoB keycaps.
One of my favorite features is the trackpoint on the right side, which makes precise mouse control effortless. The compact design is perfect for my setup, allowing me to maximize desk space. I also love the large thumb keys—they’re easy to reach and make typing incredibly comfortable.

I think this is the best keyboard if you want a left pointing device with a low profile setting. The build quality is also super nice, I have been using it for 6 months and am quite happy with it.

I'm in love with the Keyball. Been using it as my complete keyboard and mouse replacement and I can't imagine going back now.

I got the build service by Idan aswell, and everything came out great. Idan has also been great as support post sale, whenever I have any questions or issues.

Happy with my purchase!

It's very nice quality. I am very satisfied with it. I recommend you

1. Very effective for alleviating round shoulders.
2. The spacious middle section allows for placing items like a tablet, which is very convenient.
3. It’s also compatible with the Aten KM switch, making it perfect for those who use multiple computers without any hassle.

Really well built board, and when I had some slight issues upon delivery, they were quick and responsive tover email and we got the problem sorted in no time. As a ten‐year custom board builder I couldn't be happier with my first time using a supplier's build services. They were also incredibly quick addressing questions about stock and shipping times to Germany were much faster than expected. Will buy from HolyKeebs again in the future.

I used a few other light weight choc switches before, but those (both the 20g and the 35g) are just straight up better, much smoother (not scratching at all), and much quieter.

I used to use Purpz (25g) and Light Blue (20g), I really like the 20g nocturnal, they are my daily driver - however the 35g are also very nice, I can type them without "bottoming out".

Also the seller has very good customer service, cheers!

I tried a few MBK sets, and CFX sets, and even 3d printed Chicago Stenographer, this DDC profile is definitely my new favorite, the slight curve in the middle of it really fit me well, it "hugs" the fingers just a little bit, which help with positioning but still allows "sliding" on them with ease.

Also they look really nice, even better than MBK opinion.

Also also seller has the best customer service I ever received :)

I really love the design of this keyboard! The most important aspect is the placement of the thumb ball. I also have a keyboard modeled after the dactyl manuform with a thumb ball, and that placement is very awkward. I have to reach my thumb for the ball, and the thumb keys are behind the ball, so I have to curl my thumb to reach them. Not so with the KeyBall! The ball itself is tucked under my thumb where it is easy to swipe my thumb across it and move it. The keys are then a bit farther away, exactly at the place my thumb rests naturally. Beauty! I included part of the other keyboard in the picture so you can see the difference.

There was a tiny loose screw that was one of two holding the thumb ball attachment to the base. I couldn't get it to tighten, and it eventually fell out. Stuck some rubber cement under there, and it's been pretty solid since. I went to "install" the tenting feet (they come with some strong adhesive and you can stick them anywhere), and noticed several more screws that were coming out of the bottom. Thankfully there was an included hex driver (there was nothing included for the tiny tiny Phillips screw used for the thumb ball assembly, and the hole was stripped anyway), and I was able to tighten most of them.

The tenting feet work better than I imagined! They're just little metal sticks with some rubber on the end, but the whole keyboard still feels really stable when in the tented position. You can see in the picture how well it rests on my laptop so I can use the trackpad when I need it.

That's the only real difficulty I've had, and it has nothing to do with the KeyBall itself. Although I love the concept of not needing to take my hand off of the keyboard to move the mouse cursor, and it does feel good for many things, I don't really have using the thumb ball down. It doesn't seem as precise as my trackball, it's difficult to "throw" the cursor across multiple screens, and takes extra effort to scroll a page (gotta hold down a key while I scroll vs just swiping with two fingers on the trackpad). In addition, scrolling can be an exercise in frustration when there is a page that is wider than the window, as well as taller. On the trackpad, I just move my fingers to the side, and it smoothly scrolls sideways as well as down. I cannot seem to get this same sort of experience on the trackball. Either it zooms all the way to the side accidentally, or it doesn't go to the side at all. But, this is not a problem with the KeyBall specifically.

Idank at HolyKeebs has been amazing! I ask all sorts of noob questions on the Discord, and they get back to me pretty quickly. Sometimes the answer is to look elsewhere, but for the most part, they have been incredibly patient with me and amazingly helpful; I appreciate you, Idank!

Finally, production and shipping was quite fast, just a few weeks from order to it arriving at my door. Great job, HolyKeebs!

HolyKeebs repeatedly goes above and beyond to work with orders and ensure that the purchase and build goes as smoothly as possible.

This trackball case has a better shape than the stock trackball holder that comes with the keyball. I prefer it to the stock one as the ball does not pop out when swiping to move the cursor up and down.

As it is a different material, the original screws don't hold it as securely as the stock one, but I think a slightly bigger screw might do a better job.

Really happy how it turned out. Thanks!

Ordered an assembled lily58 with the case and I absolutely love it! The finish is nicely done! ldan is very prompt in replying to my enquiries as well. Overall experience is really great. Definitely ordering my second ergo keyboard from Holykeebs.

All my parts are here and in good condition!
