Silent and comfortable
The Milk POM switches are surprisingly quiet and very comfortable to type on.
★★★★☆
Great keyboard, minor software hiccup
This keyboard is generally excellent. The hot-swappable switches are a dream, and the wireless performance is really solid. I like the range of RGB options. My only minor issue was getting the Keychron Launcher web app to recognize the keyboard consistently at first; it took a couple of tries, but once connected, remapping was easy. It's a great product overall, very well built for its size.
★★★★★
Perfect for Mac users

★★★★★
