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!


This keyboard is beautiful. The keys also feel nice and I like the tactile switches. The lights on this board look like light through a cloud and its so pretty and the backboard is mirrored so it reflects the light in the perfect way. Couldn't recommend enough

Buy this keyboard NOW!

I have been searching for a nice mechanical keyboard for almost a year now. I didn't care much for the price, as long as it looks and sounds good. Then I saw this CoolKiller Balloon 84 keyboard - it was love at first sight. When I heard how the keys sound, I fell in love even more.

Its compact design, with 84 keys, offers a perfect balance between functionality and desk space efficiency. But what truly sets it apart is its aesthetic—it looks sleek, modern, and elegant.

I'm also too lazy to build my own keyboard and try different switches so this was perfect for me because I didn't need to mod it any further. So for those who just wants an aesthetic and good sounding keyboard, look no further.


As one of the early adopters of the balloon84 keyboard, I must say I'm thoroughly impressed. It's even more stunning in person than it appeared in the photos. The typing experience is delightfully crisp, and I love it so much!
