K4 Wireless Bluetooth/USB Wired Gaming Mechanical Keyboard, Compact 100 Keys 96% Layout RGB LED Backlit Gateron G Pro Blue Switch N-Key Rollover, Aluminum Frame for Mac Windows, Version 2

Amazing keyboard. I'm like my keys tactile and clicky and this device checks both boxes! The size is very compact and does sacrifice a couple of keys. It's impressive that I still have a number pad. I've not used the wireless feature and only connect via the included USB-C cable. The illumination options are impressive as are the onboard media control keys initiated by holding down the FN key, then pressing the corresponding function key. It has a good weight meaning it doesn't slide a round when I'm typing or moving the keyboard tray.

I’m a mechanical keyboard enthusiast, and have several, but was often recommended to grab a Keychron to add to my collection. I am currently using this model, the K4 Bluetooth with blue Gateron switches and RGB backlighting, to write this review on my phone. Of all the keyboards I own, this is my new favorite and the one I now use the most. I have owned a Dierya 60% Bluetooth (my least favorite, ? key in a weird placement), got a Royal Kludge full-size 104-key Bluetooth with white backlight (good, just bulky), and have a Royal Kludge 60% that has been my go-to for a simple portable writing keyboard. Once I got this Keychron, it pretty much replaced my RK 60% for both personal use and for work. As I typed this, the battery died, but that’s only because I use it constantly, and like to turn on the RGB backlighting for a little razzle dazzle when I’m sitting to write enjoyable. Only takes a few minutes to recharge, not long for a full recharge. It could last a week or more of constant use, without the backlighting, and several days with RGB backlighting. You can also charge it with the cable on a laptop while using it via Bluetooth on another device, which is nice. The aluminum frame is awesome, I’ve accidentally dropped it a couple of times, got the slightest scratch, and still works like a champ. It’s the keyboard equivalent of one of those old Nextel yellow brick phones, ha. Lightweight enough to throw into a backpack, quick Bluetooth connection, easy to set up and use, and definitely worth the money. I got it used, like new here on Amazon, was probably a return, and I’ve had zero problems with it. Even at full price, a worthwhile investment. The full number pad is what I wanted for my desktop trading and for inputting grades at my teaching gig. By far the best recommendation I got, and I definitely recommend it to other mechanical keyboard enthusiasts. Comes with a very professional-looking layout, but easy to customize if you dig fun color keycaps. If you spend a little extra to get the fully hot-swappable one, the switches are also easy to replace so the keyboard lasts for a long time. I’m super happy with my investment, and now use this keyboard on the daily for work and personal use.

Five stars for quality but not for me. This keyboard is fantastic. I like the build, the buttons are extremely clicky, and Everything seems super responsive and awesome. I did have to disable sleep mode and had some initial issues with setup, but after I got those resolved, I can't say enough good things about this keyboard. The only thing is this keyboard is not for me. I didn't realize that this was like a 75% keyboard, so I'm returning it and purchasing the 100% keyboard immediately. This brand seems awesome and I saved a ton of money getting the open box version of this item which came in perfect condition. It just didn't have the USBC cable, which I really didn't need. My recommendation is to get it, but also if you're used to a normal size keyboard then don't get this. Get the 100% keyboard version. This is my first mechanical keyboard ever, and I usually don't leave reviews so just let that sink in lol.

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.

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.

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.

Loving the keyboard so far, it feels very well built and has a satisfying range of RGB lighting modes. Very light key feel with the brown switches, takes some getting used to if you’re coming from a lower end keyboard but feels and sounds soooooo good. Great step up from my Corsair K55. I do not miss the extra buttons at all even as a flight sim user.

Looks and feels great. Construction is solid, keys are nice and clicky, responsive. But, seriously, functionality is crap. Keys randomly stick, enjoy those 800 repetitions of the letter q in the chat with your supervisor LOL. According to documentation, you can change the time before sleep up to 30 minutes. LOL, it sleeps whenever it wants to, 30 seconds? Yup, it's taking a nap. When you respond to the slack message, you look like an idiot because your crappy keyboard cut off your first 10 keystrokes before it woke up. In the time it took you to read the message LOL. No battery life indicator. It's bluetooth, why can't I see battery life in Windows? My cheap crappy logitech mouse shows battery remaining in Windows Bluetooth settings. Not this miracle of a keyboard, you just get to use it until it craps out and takes 30 minutes to get enough of a charge to connect again. And, get this, I bought two of these pieces of crap. $200 in the trashcan.
