K3 Version 2, 84 Keys Ultra-Slim Wireless Bluetooth/USB Wired Mechanical Keyboard with White LED Backlit, Low-Profile Keychron Mechanical Brown Switch Compatible with Mac Windows

This is a great keyboard. Note that this is a compact keyboard -- it is just a little smaller than a standard sized keyboard, but it is made really well, with a metal base plate -- feels very sturdy. The keys feel great and the backlighting helps see the keys in the dark. It connects via USB or Bluetooth, and can switch between three different devices with a keystroke. Also comes with key caps for both Mac and Windows.

As a "fussy keyboard user" I buy many keyboards at no expense spared. I'm not sure there's any keyboard I like much more than this at any price. I bought this for travel but really I may use it all the time. The price, basically if it was about two times the price it is, I'd still pay it. It appears to me much better made than, say, steel series keyboards at 3x the price. (And steel series keyboards flake out after a year.) As everyone has said (a) it feels rock, rock, rock solid, strong and heavy (b) it's super-low profile (c) the connectivity is perfect (I normally only go for wired, so I'm very critical of anything bluetooth) (d) every product feature is perfectly thought out. My only SUGGESTIONS for the product team. Just add a sticker, or white printing, on the rear of the keyboard, with the two commands one needs to know to start it up, etc. (I just grabbed a "white paint pen" and wrote the commands on the back.) Secondly, may I suggest selling some sort of "travel guard" which would be a very strong kind of clip- or slide- on guard which goes over the keys, for when you throw it in your carry-on luggage. (Imagine something that looks like an aerox mouse, with a drilled surface.) Essentially, this is a perfect product. I chose the "most quiet, fastest, zero click" blue switches and they're perfect. I am a programmer and writer so I type billions of words and command-arrow type clicks a day. I've added two "size comparison to typical objects and other overpriced keyboards", hope it helps someone

Excellent keyboard. The size, build quality, and key quality are all very good. I don’t really need all the RGB lighting modes, but there are plenty of them. It connects to devices very quickly, and I’ve had no issues with connection stability or quality. This is my first mechanical keyboard, so it felt unusual for the first couple of months, and I still occasionally hit the wrong keys — mostly because of the compact size. Overall, though, everything is great. Personally, I would choose slightly heavier switches to avoid accidental key presses. The battery lasts about 2–3 days with constant backlighting. I usually keep the backlight at 50%, and in that case the keyboard lasts much longer — about a week for me. I don’t game; I use it for work about 7–9 hours a day. Final thoughts: I recommend it. The size can be both a plus and a minus — it takes some getting used to — but the quality is impressive. I would choose heavier keyboard switches; mine are red switches.

My first mechanical keyboard(s)! Got one for work, and I liked it so much, I bought one for home too. In between, I tried a fancier one from another brand that offers a million switch options, thinking I was buying quieter switches -- but they were actually louder. At twice the price, I liked that keyboard less than the simpler K3, so I sent it back and just bought another one of these. The K3's keys (with red switches) are fast for programming and command line work. The key height is good. The keyboard Bluetooth pairs to my Mac and PC just fine, and you can easily toggle the Mac/PC layout. That said, it does take a moment to "wake up" and reconnect in Bluetooth mode (as many switchable keyboards do), so I tend to keep it plugged in via USB unless I need it wireless. I like that it has a USB connection option -- not all multi-device BT keyboards do. The key backlights are helpful, especially for nightowls, though I prefer to just keep the backlights in static mode. Maybe all the chasing light modes are fun for gaming, but I find them distracting for work. And in bluetooth mode, it somehow seems to switch the lighting mode periodically, so I frequently find myself having to cycle it back to find the static one. One-star off for that minor nuisance, but otherwise, great typing experience. If you aren't a mechanical keyboard connoisseur who needs programmability and swappable switches, this is a nice basic setup that seems "just right." If you're not sure which type of switches to order it with, I'd recommend the red switches for an easy typing experience and switches that are relatively quiet -- as mechanical keyboards go.

I love everything about this keyboard. The keys are smooth and quiet while giving a nice tactile response. The lighting and keycap colors are great. Overall, this keyboard has no weaknesses for my use.

I’ve been using the Keychron K3 Version 2 for a few weeks, and I’m really impressed. The sound quality is satisfying, key presses feel tactile and have a pleasant click without being too loud. Bluetooth connectivity is smooth and stable; I can easily switch between devices without any lag. The brightness adjustment for the backlight is intuitive and bright enough to type comfortably even in dark rooms. All the keys function perfectly, including the function row and multimedia shortcuts. The overall keyboard quality feels solid yet lightweight, and the slim design is perfect for my desk setup. It’s also highly compatible with Windows, macOS, and iOS, making it very versatile. Overall, it’s an excellent keyboard for both work and casual use, and I would highly recommend it.

Very nice but if you need a usb dongle thing this doesn’t have one. You’ll be using a usb cable (included) or Bluetooth. If you need that you have to buy the pro. Other than that it’s a great small keyboard with cool backlighting and surprisingly the keys are have backlit characters.

Update: I got the brown switch version too and liked the overall feel. After a couple weeks of use, the same glitch happened for the first time just two days before my return window closed. It would freeze up and can't even adjust the lights on the board itself, but still shows connected with 59% battery and requires power cycle to resume function. I truly enjoy the keyboard but had to return it again... I bought the K3 Version 3 banana switch and really enjoyed the switches (hard to find tactile ones in low profile boards), and that it allows customization. It's a bit scratchy but the tactile feel is good. However, I can't believe I ran into the connectivity issue as well, as mentioned by a YouTuber (Cameron Dougherty Tech). It'd suddenly become unresponsive, but still shows as connected. The keys would be completely dead and can't even adjust the lights on the board itself. Turning it off and on would immediately become normal again. It's been basically unusable due to this. It may not necessarily be a connectivity issue, and more like that the keyboard just stops working completely as I can't even adjust the lights. I really like the keyboard otherwise, thought I found a keeper, but will most likely have to return it.
