Love it - needs case

I really love it. I bring it everywhere, so wish it came with a small hard case or cover because the keys are domed, so they get pressed down more easily when putting it in a backpack sleeve. This may wear them down over time.

Beautiful keyboard, but…

I get so many compliments on how beautiful the keyboard looks. However, it constantly gets disconnected quickly, and I have to toggle it off and on sometimes for it work. Also, it’s not remappable, which sucks cause the location of the buttons are not optimal. I hope they patch up the poor software.

Thank you for your valuable feedback. Our driver is able to restore & reset key setting and lights etc. However, your insights are appreciated and will be taken into account for future enhancements.

Excellent first-time mechanical keyboard.

This is my first true mechanical keyboard choice and I am so glad I went with this one. The shipping was lightning fast and the keyboard is even more gorgeous in person. The keys are smooth and I love all the backlight options. I am surprised at how easy it is to get used to typing with this keyboard, but it truly is a very smooth and lovely experience. Highly recommend.

My favourite keyboard!

Immediately fell in love when I saw this keyboard, and when I received it, it was even more beautiful in person! It is so comfortable to type on, and it's not noisy at all. The keyboard makes me feel like I'm not working sometimes :D Super cute!
