I am writing this review on the keyboard. It's versatility in connectivity options, fantastic features and switch choices, along with its incredible size and small layout make it the ideal keyboard for me to travel to and from the office with. It's easy to throw into a back inside of it's included case. This is also the only keyboard where I was comfortable with the default layout and its many layers. Top notch word! I would not hesitate in buying another for a friend or coworker.
恥ずかしながらGeonixRev2を知らないままLuma40を買い、何台もの初期不良とメーカーとの不毛なやりとり、低すぎるビルドクオリティに悩むことになった。
GeonixRev2は偽物より美しく小さく軽い。
品質管理もされており、不愉快ながたつきや部品がすぐ取れてしまうということもない。当然間違ったネジが混入していたりLEDの不良に見舞われたりもしない。
おまけにクールなセミハードケースまでついてくるんだ。
人々に数千円の差額を惜しまない勇気があることを祈っている。
The keyboard seems well made but I have some complaints. Key caps are tilting which is infuriating and lack of official software to map all the keys was quite cumbersome to do via some websites.
Listen, I get it. It’s missing a ton of buttons. But you would be blown away how intuitive it becomes to get used to the modifier keys for the symbols or numbers. I find the keyboard more natural than a traditional staggered layout now.
The keyboard is fairly thin. Built is great for my first aluminum keyboard ever. The switch travel is around 3mm, only 1mm different than full switches. But there's few complain that I have:
1- The original keycaps either slippery or sticky due to its glossy finish. Maybe make it more matte finish. I end up using full XDA profile keycaps.
2- Bluetooth connection is weird sometime. Not suitable if you want to use multiple device. Else just use 2.4ghz dongle.
3- Need option for vial for more extra function like tap dance. I end up using a QMK fork someone develop on their Discord. Not only it give extra function and 6 layers instead of just 4. It fix the Bluetooth problem too and Im using it right now.
Since I don't know QMK that much, I use AI to write me the code. Thanks Mjuma for the qmk fork or else I would consider to return this keyboard.
