Review: My favorite keyboard I've ever owned, wrist rest needed - I love my K3. Keychron is awesome. Never had a backlit keyboard before and while it's cool it has a bunch of different light settings, I really only switch back and forth between a few of the rainbow ones. The patterns that move are distracting for work. I use this at home and bring it to work for office stuff. Travels well and constantly gets people talking and asking. Easy to type on. Haven't had a problem with Bluetooth at all and typically BT devices mess up every now or then for me - The K3? Not once! Great battery life, but I use it plugged in when working. Wired and wireless work similarly. Love the switch that lets you go back and forth between the windows and mac keyboard - a huge plus for work. After typing for hours, my hands were very fatigued - this was remedied by picking up the matching Keychron wrist rest. A small rest made the world of difference. When I look at this keyboard it makes me happy that I finally bought a cool keyboard - and the one that I wanted that I liked. Would recommend Keychron to anyone. I don't like the auto sleep feature, glad you can turn it off!
Review: Outstanding typing experience - This is simply the best typing experience I know. I replaced the brown switches with blue ones, and now I find myself pressing keys for no reason. The feel, tactility, and feedback is just incredible. I'm also very impressed with how easy it is to change the key caps and switches. The build quality of the keyboard is top-notch. It feels firm, sturdy, and generally well-built. And the feel of the keys is sublime. You can tell people who care put a lot of thought and effort into designing this product. The configurable RGB lights are a cool party trick. It's one of those things that would make using the keyboard fun overtime. I've settled on a red backlight. The only con I experienced is Bluetooth performance. Connecting via Bluetooth is not fast. However, Bluetooth in general has a reputation for being finicky. For now, I've opted for using a wired connection for performance reasons. Color me impressed. This is my first mechanical keyboard, and I'm now a fan. I don't think I'm going back. For Linux users, this works perfectly on the platform. I use Fedora Linux.

Great keyboard for daily or work use. The brown switches are quiet but still have a satisfying click to them. The RBG backlit is beautiful and the features are really cool. Great overall keyboard.
