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.
