K4 Wireless Bluetooth/USB Wired Gaming Mechanical Keyboard, Compact 100 Keys RGB LED Backlit Gateron Brown Switch N-Key Rollover, Aluminum Frame for Mac Windows, Version 2

This keyboard is a great mechanical with a nice solid quality feel. In general from the standpoint of typing there’s nothing to complain about. The RGB backlighting is effective with many pleasing patterns and color choices. Battery life seems more than adequate and the device will charge while being used in wired mode. The only complaints I have relate to the speed with which it switches between devices. For the typical user this probably wouldn’t be an issue but for someone that’s switching multiple times within very short intervals the lag is enough to become frustrating. The switches on the side for selecting wired or bluetooth and Windows or Mac are small though not frequently used. There is no software which is both a positive, (you don’t need any) and a negative because there’s no key customization. Your only indicator of battery life will be a small led next to the small selection switches not a deal breaker but not ideal either. All in all I recommend this keyboard, it offers the benefits of a mechanical with good tactile feedback, support for 3 devices, nice RGB backlighting at a very fair price point.

LOVE it. Small footprint, and very sturdy build quality that will probably last me longer than any other keyboard I've ever bought. Bluetooth maintains connection very well and the key-feel is GREAT. I can type fast during Zoom calls for work and the noise doesn't disrupt the call. Some reviews say that some of the RGB backlighting options are distracting... but you don't have to use them if you don't like them! I leave mine set to a gentle amber glow that makes the keys highly readable, but if you like fun rainbow colors the option is here, and they're quite bright. I would have absolutely purchased a version that supports Razer Chroma if that were an option... (maybe that's proprietary to they but overall this is the best keyboard I've ever owned.

I got this keyboard because I am doing college online and I have limited desk space but needed a 10 key for using graphing calculators. It is very compact, it's only about two cap-widths longer than my 60% keyboard and about 1 wider. I do have issues finding the arrow keys and I wish they would have used caps with a nipple or some other distinguishing mark to make them easier to find without looking. But I'm sure with time muscle memory will make it much easier. The reviews that mention a lack of num lock indicator must be old as the model I was shipped used a red led to indicate capslock and numlock status. The key caps feel like POM instead of PBT and I (subjectively) don't like POM caps nearly as much, but they are fine otherwise. I have the brown switches and they are very nice. It is extremely sturdy (if you get the model with the aluminum frame) and the lighting can be controlled completely on the keyboard so no software required. The Bluetooth pairing is quick and easy, have not had any dropped inputs or other issues. I wish the aluminum frame was available on the non-rgb version. I don't like RGB and I don't use it. I also wish there was a model with no lighting (except for num and capslock). I also don't like that the default caps are for MacOS, but they are easy to switch. I wish that they would have left the insert key, I do actually use it, but instead the key is the dedicated RGB key. I keel like retaining the insert key and making the RGB be a fn key would have been more sensible.

I bought this mechanical keyboard after my Mac keyboard went bad, it's been holding up pretty good. I love the sound and feel of the keyboard the RGB lights I got the version with the brown switches. The RGB lights are pretty cool however they are more or less just decorations. I find that the lights do not illuminate the keys enough where you could properly use the keyboard in a dark area. It's like the RGB light don't shine Through and illuminate the keys enough. The best option would be to use the white lights as the RGB is a bit weak or not good enough. I love the customization of the RGB lights I also love the Mac and windows compatibility. The keys are beautiful. Keyboard is minimal. It's not too big and it's really heavy. It's not gonna be moving around your desk as you type. I get maybe a week of battery life, that's probably because I always have the white lights on. Happy that they included a USB cable, however, I am not happy that one is a USBA and not a standard USBC cable.

I purchased this keyboard when searching for a slightly more compact keyboard that still had a 10-key number pad. I had originally not cared whether I purchased a mechanical keyboard or not, but I'm really glad that I did. The first thing that struck me about this keyboard when taking it out of the box was the aesthetics - it's a rather pretty keyboard with a nice weight to it. I purchased the version with brown switches, so I still have a "hump" around the articulation point which feels incredibly satisfying to type on without the clickiness of blue switches. The weight of the switches feels great. Setting up Bluetooth was extremely easy and I was paired to my computer within a few seconds. I do prefer to use the provided cable and run a wired setup when working at my desk (laptop docked to a larger monitor), and as such I haven't been able to push the battery to its limits but I'm sure it will hold up fine. There are loads of rather dynamic backlight setups to choose from and cycling through them is extremely easy. I prefer a simple solid white backlight but for those looking for more RGB options this keyboard will suit those needs. Admittedly, my use case is simple enough that I can't speak to key mapping or any of the more advanced features this keyboard offers, but I would wholeheartedly recommend this keyboard for anyone looking to try out a mechanical setup to see if it's for them.

I bought this for use with work. I wanted something quiet and yet still tactile as I would be doing a lot of typing. I did not rate it for gaming as I have no plans to use it for gaming. However I am sure it would do fine as a gaming keyboard. As my title said, this keyboard has made me much more critical of other keyboards. For the price, it's an incredible value. Buttery smooth switches with a very subtle and nice tactile bump (I got the brown switches). The dampening is phenomenal so there is no rattle. Lots of lighting options without need of software, if that is your thing. Now I have a hard time choosing a gaming keyboard cuz I now have a new standard for how keys should feel. Something I would have liked a wristrest. They do sell one separately, which i am sure helps reduce cost for the keyboard itself, however the bottom side of the keyboard is not magnetic so you may have trouble with it moving around if you have your keyboard on a plush deskpad like myself. Also, the model i got had Gateron G Pro Browns. I love the feeling, but they really are a switch meant for heavy handed typing. I do sometimes miss keystrokes cuz i stop when i feel the bump, but the actuation point is a little bit past the bump. For use for purely typing, I am gonna have a hard time finding something that beats it but I would recommend the hit swappable version to easily switch them out if needed.

I really wanted to love the Keychron K4. The build quality? Brutal—in a good way. Solid, heavy, feels like it could survive the apocalypse. Unfortunately, that’s where the compliments end. The battery life is downright embarrassing. Even with the LEDs off (yes, OFF), the thing acts like it’s on life support. And if you use it with a Mac, good luck. Every time you try to log in, it’s like the keyboard goes on a little vacation—delay, delay, delay. Then, once you’re in, it decides to hibernate again, just to keep things interesting. Basically, it’s never awake when you actually need it. Using it quickly turns into a nightmare. Waiting for it to “wake up” makes me feel like I’m using dial-up internet in 2025. Bluetooth connection? Fragile at best. And when you compare this battery and connection performance with cheaper keyboards—ouch. So yes, it looks and feels like a tank. But functionally? It’s more like a tank with flat tires.

This keyboard is simply fabulous. Extremely comfortable to type. The keys are hot swappable and have great feel. Nice and compact form factor. But the killer feature is the RGB lighting effects. They are just brilliant and transform a humble keyboard into a showpiece for your room. It's basically a keyboard and a lava lamp at the same time. Looks amazing in a dim room.

The Keychron K4 v2 is awesome! Bluetooth connection is smooth, and you can easily switch to wired mode when needed. The brown switches feel tactile and perfect for typing without being too loud. RGB lighting looks great, and the aluminium frame feels solid. Compact layout saves desk space, and it works perfectly on both Mac and Windows. Overall, a really versatile and well built keyboard.

love it

Gostei muito do teclado. Ele parou na alfândega, mas o vendedor realizou todos os procedimentos rapidamente para que o teclado chegasse. Mesmo com essa parada não prevista, ele chegou dentro do prazo informado na compra. Estou usando-o há alguns meses agora e continua perfeito. É importante lembrar, para quem não percebeu, que esse teclado não é ABNT2.

Es un Muy buen teclado mecánico.

As my first mech keyboard, I was nervous about spending this much money on a keyboard, but as a tool that I use at least 8 hours, 5 days a week, I'm glad I made the purchase. The keyboard not only looks great, but feels great too, and the battery lasts a week even with the backlights on.
