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

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.

This was my first purchase of a mechanical keyboard since back in the day. If you're old enough for the 286/386 computer days, the feel may bring back some nostalgia. I love it! I was not sure which switches I should buy (red, blue, brown). I decided to go all out and get the blue ones. I am not disappointed. It is very clicky. It may not be good for stealth typing while on Zoom or Teams meetings, but for me it is great. Take a look at the switch chart to help you decide. I went with the aluminum frame. It is solid and feels like quality. I haven't changed the rgb lighting at all because I like the waves of color that it opened up with. Some day, I'll explore the other options. I like the way the lights shut off after an idle period, then come back when you begin to use it again. I am 100% satisfied with my purchase.

Listen, this keyboard worked flawlessly. Nothing wrong with it at all. However, I was use to a fullsize keyboard ( been using computers since 1988 ) and I've never had a 50% or 75% keyboard before. I needed one for my M1 MacBook, so I bought one off a YouTube recommendation.. they all recommend this keyboard and when I got it, it was just WAY too compact and squeezed together for me. Also, I didn't like the wireless setup. I'd get up from the desk for like 20 minutes and come back and start typing and nothing would happen and then the keyboard would wake and be able to type again. At first I didn't mind but after repeated happenings, I decided to return the keyboard since it was too small also. I did stick with the same company though on the new keyboard. I got a k10 instead which is a fullsize keyboard and I also kept it wired in so no more issues. This company is great, the keyboard was fine.. it just didn't "fit" me so I got the larger k10 model and that solved everything!

The battery life is pretty long dont have to charge it for about 2 weeks but The only thing I disliked was once the keyboard died it took a while for it to turn back on with Bluetooth but that’s more of a user error regardless of that it feels/sounds amazing and it’s the best keyboard I’ve gotten a bit pricey but it’s customizable to your liking highly recommend it

Pros - It looks really good - it is not a cheap, flimsy keyboard, it is sturdy and quality. - There are plenty of RGB lighting option you can toggle through - Packaging is done meticulously. It almost feels like an Apple device when it comes to packaging - Blue switch sounds good but it doesn't sound expensive Cons - Bluetooth is useless. Sometimes it is not reading the strokes, sometimes it is reading it 20 times and making typing a struggle so you have to use it with cable all the time to prevent that - RGB lighting is almost not visible during daylight. It is not powerful and bright enough to enjoy the colors in a well- lit room - No macros Conclusion, Cons overweighed the pros for me and I decided to go with Logitech G815 keyboard and that keyboard is only $50 more expensive but it is at least 10 times better than this one. G815 doesn't have any weaknesses.
