I love this thing. Super solid design. The software is easy to use to configure your layout however you want.

I eventually ended up swapping out the stock switches and keycaps to something more my speed. I also eventually flashed QMK onto the microcontroller so I could setup some more advanced features that the software didn’t allow for.

The Atreus is very fun to use and customize! I have clear keycaps that allow you to put anything you want underneath them, and I cut up sections of a book to give the keyboard a cool visual, and also to reference what other layers exist (for example, e, 3, and # existing on different layers but all labeled on one key). I ordered this with clicky switches, and swapped them for tactile ones. I kept clicky switches under the two keys that adjust the layers so I can hear when I press them. Overall, this keyboard is awesome. It's unique and fun to use!

This is a fantastic piece of equipment. Of course, in the beginning it takes some time to get used to, but I'm totally dependent on it now (and lost when typing on my regular notebook keyboard).

The main reason I tried the Atreus was that, as a programmer, I struggled to reliably blind-type numbers and the many symbols that have to be typed with the right pinky. On the Atreus I can rearrange all those keys to comfortably and reliably type them. In that respect the switch was very much worth the effort. On trains, I can keep my computer on the foldout table and the Atreus on my knees, which is much more comfotable than typing on the computer's builtin keyboard.

Build quality is very high. One word of caution: this keyboard might lead you down a road of eternal tinkering with keymaps, switches and keycaps :-). My pro tip: If you buy blank keycaps with a cherry profile, you can vary the angle of the keycaps on the bottom row depending on whether you intend to hit them with a thumb or a finger! Also: USB-C cables with angled connectors are great.

It is a remarkably compact keyboard, and it is perfect for me for daily use. The layout is awesome designed to minimize wrist strain (I usually have wrist issue with my previous 40% keyboard).

The really big plus for me is it ship with preinstalled QMK firmware, a keyboard firmware that I cannot live without. I've even managed to eliminate the use of a traditional mouse, relying solely on QMK's mouse key feature.

For the cons, there is room for improvement in terms of connectivity. I'd prefer to see a native C-to-C cable compatibility and potentially a Bluetooth feature to enhance its versatility, like some other models on the market. Despite these minor issues, the Keyboardio Atreus truly stands out in terms of comfort, functionality, and most importantly, user experience.
