KeychronK3 Version 2, 84 Keys Ultra-Slim Wireless Bluetooth/USB Wired Mechanical Keyboard with White LED Backlit, Low-Profile Gateron Mechanical Red Switch Compatible with Mac Windows

I've been looking for a slim TKL mechanical keyboard for a long time. I've read about the Keychron products, but hesitated to pull the trigger because other brands had more reviews with similar ratings. I shouldn't have and hope my review will help others who are relying on the number of reviews to make an informed decision.This little beauty is the best slim TKL mechanical keyboard I've tried by a long shot! The form factor is perfect, quality is great (especially given the very reasonable price) and it feels and works great! I might end up buying one or two more, one for the office and the other just so I have a replacement for when this one wears out. I have not tried using it in wireless mode or using it with a Mac. The default key configuration is for Mac, but there are spare key caps to replace Mac specific keys with Win (which I promptly did :) ). It is small enough to leave plenty of space on your desk, yet heavy enough to not move about when you type. The keyboard comes with brown mechanical switches, which are smooth and quiet enough to not annoy people sitting around you.All keys are mapped correctly to their designated functions. I'm actually using it with a Chrome book, was super impressed that all the keys do what they said they would, even the screenshot button.All in all, I've very happy with my purchase - great product Keychron!

I've used a lot of keyboards going all the way back to the original IBM PC. Most modern keyboards feel mushy to me. This feels great.I bought both the brown and the blue switch variations. The blue had a great feel, but its relatively high-pitched click was annoying. The brown is closer to a Goldilocks switch, quiet and with good tactility, although just a tiny bit mushy. I chose the K3 for its low-profile design, as I had read that the standard Keychron keyboards are very thick and need wrist rests. The K3 at only 7/8" thick feels fine without one. Key travel is also quite good. Fresh out of the box, I don't seem to have lost any typing speed compared with the MacBook Pro keyboard which I've been using for the last few years.I haven't had any problems with the Bluetooth connection. I have it paired with three devices – an iMac, a MacBook Pro and an iPad Pro. Just a few seconds each to pair initially, then no trouble with any of them. Switching between devices takes just a couple of keystrokes. As a Mac user, I really like that the media function keys work out of the box and are labeled properly. Likewise the command and option keys. I have no real need for the backlighting and certainly not for all the fancy, flashy chasing light modes. It's a keyboard, not a theater marquee. But I do find it handy to have on at minimum brightness when I have to work in a darkened room.If there's one thing I wish Keychron offered, it's a low-profile numeric keypad to go with this. I didn't want a full-size keyboard like the K5 which would force me to reach pretty far for my trackpad. But a numeric keypad comes in handy when I have to type in more than few digits, and it would be nice to have one to put to the right of the trackpad.

This keyboard is really nice to type on, especially compared to the mushy membrane keyboards I'm used to. I got the brown switches which provide a tactile bump to them without being noisy. The keyboard is the perfect size to minimize mouse reach but it keeps function and arrow keys in the layout. It looks nice and blends in well with my setup. The removable keycaps makes cleaning a lubing easy. They also have a somewhat matte finish that feels and looks nice

Mechanical, but feels more like a laptop keyboard than a bulky mechanical (Good thing in my opinion)The Bluetooth switching is the main purpose I got this and it works flawlessly when connected. Bluetooth was annoying getting my devices to connect for the first time, no issues after that though. (Had to put the keyboard on top of the devices until they synced)No issues with battery, or input lag as other reviews concerned. Using this in place of my Ducky One-2 keyboard now.

I think it's a great keyboard for the money. I use this for my work as a programmer and for personal use and maybe a bit of gaming.This keyboard suits all my needs and fulfills them very well.The switches themselves are (again, in my opinion) amazing! they are not like standard brown switches, they are much quieter and they maybe feel a bit mushier than the usual full-sized brown switch but I really like that. The switches are tactile and fast and yet very quiet (compared to other, even low profile keyboards) and still maintain that mechanical keyboard feel.Both the Bluetooth pairing and the cable modes are great. The pairing is quick and has no issues and the cable mode is good as well.The keyboard size and functions provide a perfect experience with minimal footprint for every need (programming, general use, and gaming).The only downsides maybe are the slightly short battery life and lack of software (to enable things like macros, etc.).The build quality is just OK and could be better as well.All in all, considering its price I think it's an amazing keyboard, I rated it with 5 stars and from using 2 different more expensive keyboards I switched to only using that one.

This sleek keyboard has great-feeling keys and excellent battery life. Its red switches are suitable for fast typing and don't make much noise. The packaging includes a transparent plastic shell to protect the keys inside the cardboard box; I use just that plastic shell when traveling with the keyboard in my backpack. For the price, this keyboard is incredible. It's way nicer than the Satechi Slim X1.
