My Fave New Keyboard

I’ve had this keyboard a month or so now. Everything about this keyboard is fantastic. The look, the feel, the sound…. I love it! The software for customizing is ok, but I love that it has an internal memory so I can set it up on my home PC then use it as I customized it on my work PC. I do wish it had an “end” key, but it’s not a deal breaker since I can still use the keyboard shortcut for that function. It’s solid, heavy, a quality build for sure. The sound is almost like freezing rain on a tin roof, and not too high pitched or “clacky”. If you’re hesitant, just buy it. The shipping takes a while, about 2 weeks for me, but worth the wait!

Love ittt

This is the most beautiful keyboard I’ve ever had. It satisfies my hobby of decorating my workspace, helps me relieve stress, and I really enjoy the sound of typing

Good look, sound and good switches. Terrible placement for brand name and low quality keycaps

Keyboard is good and the aluminum is pretty clean, mine had one ding- not cool, but the cost warrants looking over the issue.
Keycaps are the worse I've seen in a keyboard- just dont put keycaps and drop the price, let people choose their own keycaps.
The brand name placement is terrible. No one wants to see that and should not be front and center. IT IS TERRIBLE. It should be small, somewhere in the corner on the back of the board if you really want to place it somewhere, otherwise, leave it out!.

Package contents are great, and felt like good quality, would have preferred that money spend on better keycaps and the keycap puller and switch puller and and nice cable.
Most people have USB-C cables and if someone buys keycaps, they usually come with a keycap puller so not really needed.

The switches sounded decent for the price. Lubrication of the stabilizers could be improved.

Great Product

This is a very good product and definitely a smart choice. I'm very satisfied!

Healing Sound and Gorgeous Looks

The sound is so soothing—it’s honestly therapeutic. It needs to be charged, which I didn’t expect, but the moment I saw a blogger using it, I ordered one right away. I didn’t expect it to be this beautiful 😻

Solid Aluminum Build

The unibody aluminum design gives it a flawless, seamless aesthetic. It’s truly a thing of precision and beauty.

Quiet, Stylish

I bought this for office use, and the sound is very quiet—no worries about disturbing others. The touch feels great, and typing is effortless. Most importantly, it looks amazing. With the right lighting settings, it gives off a low-key but super cool vibe.

Must-Have

This keyboard is absolutely beautiful—like a piece of jade, clear and flawless. The typing feel is excellent, and even my coworkers couldn’t resist tapping a few keys when they saw it. As a female programmer, how could I not have such a high-quality and stylish keyboard?

An Icy Dream Come True

The CK Polar Bear is absolutely stunning—it feels like it was made just for me. It’s as clear as ice, and the typing sound is crisp like ice cubes clinking together. Typing on it is pure enjoyment. With customizable lighting and the ability to DIY a new color every day, it feels like owning several keyboards in one. Even the aviator cable lights up! Totally worth the price—I’m completely in love. I’ll definitely come back if I need another one. Five stars! Also, shipping was super fast.
