Keychron K3 Ultra-Slim 75% Layout RGB Backlit Wireless Bluetooth/Wired USB Mechanical Keyboard, Hot-Swappable Low-Profile Keychron Optical Brown Switch 84-Key Gaming Keyboard for Mac Windows-Version 2

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.

Very sturdy keystroke action. I'm very lucky to have this now that my "L" key died on my Surface Book 3 died. This Keychron keyboard is almost a drop in replacement. The key action is better than the laptop action, and the optical switches are rock solid.

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!

So, I just got my first legit mechanical keyboard, and I went for the quieter one with red switches. It's pretty light and slim for a mechanical keyboard, but if you're into super slim ones, maybe skip this. I got it mainly for the feel while typing. Honestly, if I tried it in a store, I might've gone for something a tad clickier, like the brown switch. The materials are solid, you can switch out the key caps for Mac or Windows, and the light effects are pretty cool. Plus, it's a comfy keyboard. And despite being on the cheaper side for this type, it doesn't skimp on quality. Overall, it's a great deal. If you're all about that clicky feel, go for the brown switch. If you still want the mechanical vibe but a bit quieter, red switch is the way to go. But be warned, the blue switch might be a bit too clicky for some.

The size on this thing is great. I really like the responsiveness of the keys. The RGB lighting is lots of fun, and really great in low light settings. I only use it plugged in as I am using it for gaming and don't want the battery going dead mid-fight. MAKE SURE YOU HOLD FN+K+C FOR 3 SECONDS UNTIL IT FLASHES! This will let you use F5 and F6 as normal keys. If you don't do this they will be set for backlight adjustment. Also, read in the book how to set your backlight to stay where you want it. I kind of want to get one in a full size for my office, but I don't want to spend the money.

Very disappointing experience on Mac. Whenever I come into my office and turn on my Macbook, the bluetooth either doesn't connect or the battery has died. Why does the battery die every day? Or why can't it reconnect? Good luck figuring that out. There is not battery indication, and no way to debug why bluetooth won't reliably connect if it's not a battery issue. There is supposedly an auto-power off function that you can activate with a key press. Does it work on this model? Who knows. Is it enabled or disabled when you press the key combination? With no feedback, it's impossible to tell. Even when I plug it in via the USB-C cord and switch it to "Cable" mode (why do I have to manually flip a side to do this? Again--who knows), it's barely functional. Many times when I begin typing, it simply doesn't respond at all. I wait a second or two and begin typing again, and then it does work. But there is at least a dozen times throughout a typical day where I have to pause typing and wait for the keyboard to un-freeze itself before I can start typing again. I like the look and feel. The keys are nice, the size is nice, the keys are just tacticle enough, and overall this is a keyboard I want to keep using every day. Sadly, it's inability to hold a charge, reliably connect to my Macbook, and its constant unresponsiveness throughout the day has been a major annoyance ever since purchasing this keyboard. I literally just leave it plugged in due to how unreliable it is at connecting via Bluetooth. Sad.

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.

Compared to other mechanical keyboards this is a good deal. I like the low profile, and so far I like the optical switches. In fact even though this came with the brown I bought some banana and blue switches just to try them. So far banana is my favorite. The keyboard feels sturdy and solid. While some don't like it, I am a fan of the RGB. It lacks software to program it, but I don't miss it too much. Bluetooth seems to connect fairly quickly for me. I do wish the usb cable came out the side like the other Keychrons I have or have tried, but that's not really a problem. The ABS keycaps seem to get dirty super easily, and they feel like they will shine up a bit before too long, but for the price I wouldn't really expect anything else. Overall I'm very happy with this purchase.

Item exactly as described, Its perfect and I love the keyboard. Been using it for months now and its amazing

It is one of the best mechanical keyboards out there. Don't think too much as it ticks most of the boxes: 1. Perfect typing (you will get a few errors in the starting but once you get used to it - it will feel amazing) 2. I went ahead with brown switch version - it gives you a good tactile feedback (unlike red switches which have minimal resistance and you won't know when you accidently typed or pressed something). 3. It is really silent. The low-profile really tested out. I am typing this review late at night and honestly, there is not a lot of sound. I think my laptop keyboard would make more sound than this keyboard. 4. The option to switch between mac and windows is great. Although I am a windows user - the added functionality is welcome. 5. The additional ability to switch between Bluetooth and wired is amazing too. However, I have only tested the Bluetooth on my laptop and have not used the switching feature to connect to other devices. 6. The RGB light has a range of different combinations to set it as per your liking. I only use one type of lighting which is the static one. RGB does not hold that much importance for me but if it is a deal breaker for you - this keyboard will not disappoint you in that department.

Este fue mi primer teclado mecánico y aún lo sigo usando después de dos años. Es un teclado delgado, ayudó mucho a que mis muñecas dejaran de doler cuando tengo que escribir todo el día. Es ultra compatible con Mac, así que no tendrás problemas al usarlo, además puedes cambiar desde el teclado el sistema operativo donde lo estás usando, lo cual permite que cambies de uno a otro sin problemas. Otra funcionalidad excelente es el cambio de dispositivo cuando lo usas en el modo Bluetooth, puedes usarlo en la computadora y cambiarlo rápidamente a tu iPhone o iPad funciona perfectamente. Si te preocupa que el layout es el de Estados Unidos, no hay nada que temer, solo configura el idioma correctamente en tu computadora y después de usarlo un par de días estarás escribiendo como siempre sin necesidad de ver las teclas. Algo a tener en cuenta es que si esperas luces brillantes, este no te las va a dar, si bien en un ambiente oscuro los colores y patrones son atractivos, si usas una lampara en tu escritorio estos dejarán de verse. También debes elegir correctamente los switches, yo lo compré con los color café, porque no quería que hicieran demasiado ruido, pero al final no se sentían tan cómodos y el sonido es realmente imperceptible, terminé cambiándolos por unos azules los cuales se sienten mejor al momento de trabajar y tampoco terminan haciendo un sonido realmente fuerte. Leí algunas quejas sobre el material de las teclas, pero en realidad no están mal, cuando lo compré no veía muchas opciones para comprar teclas de perfil bajo, pero ahora hay un montón de donde escoger. Sinceramente lo recomiendo.

Esse teclado realmente me surpreendeu nos primeiros dias de uso, apesar de ser um teclado menor, as teclas são perfeitamente configuradas para digitação, como programador, produtividade aumentou... O conforto dos pulsos ficarem tão perto da mesa devido a altura e estrutura slim do teclado é surreal de bom, teclado me surpreendeu muito. Estou usando a um dia só, vamos ver daqui alguns anos... Um contra que nem é tão contra: é ótimo o multidevice, mas demora de 3 a 5 segundos para mudar de dispositivo (talvez eu esteja querendo demais)

the product is in German layout. The seller is misguiding the customers. The product is not slim as advertised, I compared it with Lenovo professional keyboard. also the build quality is very poor compared with my Lenovo keyboard. returned the product. waste of money.
