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

This keyboard was built for me. I love low profile caps, I love a tactile click, I love the sound, and I love the RGB options. I tried a Logitech keyboard with Romer-G switches, but those keys were too mushy. I tried a Razer keyboard with green switches, which had an awesome tactile click, but the noise was awful and pingy. Then I tried this keyboard. This keyboard is awesome. I bought the blue optical switches, and man are they perfect. They have an audible click, but since they're low profile it's a quieter, higher pitched click than usual blue switches. They also have a nice, short actuation height. And the keycaps don't hit the keyboard since they're low profile, so it's quieter than a normal blue switch. The RGB on this keyboard is sufficient for what it is. It's not fully customizable, but there are plenty of options to cycle through. Personally I think the teal looks the best on it. It's not super bright, either, but it's not too dim. It's just going to be dimmer than your typical "gamer RGB." I have a Razer mouse and charging station, and with the brightness on those set to 15% they match the keyboard pretty well. I like RGB, but I don't like distracting RGB, so it's perfect for me. The keyboard itself has a very modern, minimalist design, so it looks good with any setup that has decent cable management. I also love that it's Bluetooth - it's only behaved strangely for me once, but after a bit of problem solving I discovered it was my fault. When in Bluetooth mode, I notice no perceptible delay in key press and response on screen. The battery life on this keyboard is good - I usually get away with a week (sometimes a little less) between charges, and I'm a full time college student who writes at least one essay per week and games for about 10 hours per week. And this charges fast - like two or three hours to full charge. My only complaint is that the LED that warns you when the battery is low is on the back side of the keyboard right next to where the USB cable plugs in. I usually don't even notice it's blinking while I'm using it, and there has been one time where the keyboard shut off in the middle of a game. I wish they had placed it somewhere more visible, but I realize that would be hard to do with such a minimalist keyboard. Overall, it's an amazing wireless keyboard that performs exactly how I hoped it would. If you like low profile, clicky keys, I fully recommend buying this.

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.

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!

I gave this keyboard 4 stars because the Bluetooth seems to not work great. I have a 2019 MacBook Pro that I use and for all of my other devices the Bluetooth works great but this one struggles to type sometimes. I use it wired now so it stays charged and I don’t have to worry about the Bluetooth not working.

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.

I bough it twice and returned. Bluetooth switching takes too long. And there is lot of keystroke lags. Only time it worked well was when I brought my laptop and Mac mini closer <1feet.

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.

Es un teclado para mi gusto de muy buena calidad, bonito diseño, fácil de transportar, el uso que yo le doy es para programación y diseño. Por mi parte lo recomiendo más para trabajo que para gamers.

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.
