The build quality is decent. Feels firm, no flex when typing, decent dampening. However, the switches pull out easier than the keycaps. With the exception of the most-used key, the spacebar. There’s no stability brackets on the spacebar, so it loosens left or right, depending on the last thumb to strike it. It’s constantly misaligned as a result and needs regular centre-presses to re-seat to the space bar switch.
Bluetooth connectivity is strong and hasn’t missed a beat. The RF adapter is USB-A, so expect to use an adapter or dongle for any modern laptop or Mac.
USB-C direct wired connection is good, and the port is on the top-left, aligned with most Mac laptop ports. Battery life has been good so far as well. Lighting effects are lacklustre and you’re going to want to make your own.
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.
