Excellent slim keyboard with great features
Iâve been using the Keychron K3 Version 2 for a few weeks, and Iâm 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. Itâs also highly compatible with Windows, macOS, and iOS, making it very versatile. Overall, itâs an excellent keyboard for both work and casual use, and I would highly recommend it.

Fantastic keyboard and well priced
After watching a Bitwit video where he said this is still his favorite travel keyboard (he was flying), I found an open box of the same model and figured I’d give it a try for not only my laptop but a SFF for travel.Kyle was spot on. I absolutely love this keyboard.For the price, it is better than many more expensive models (I’m looking at you Razer). The value is fantastic.Unlike many portable keyboards, it has much better key travel along with both Bluetooth and USB capability. Good click, backlighting and quiet sounding keys.I like it so much I plan on picking up another one for my wife to use with her laptop.

Keyboard product design is a fine art. And this is the masterpiece.
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

Very Good Office Keyboard
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.

Best K-series Iâve Had
I love the slim design of this keyboard so much more than the previous K2, it weighs so much less and really skyrockets the mobility for myself. Iâve never liked the RBG functionality on these keyboards – it always seemed so out of place for it, so the white backlight only is perfect for me. I had switched from my previous K2 to a few other keyboards over the years but it was nice to come back to the K3 and feel right at home with the keyboard layout. I use both Mac and Windows machines so I love having the option to switch (I wish they made hybrid keycaps though!). The keys donât feel lacking despite their new slim design, it still has excellent travel / tactile feel. Bluetooth is solid. I think its excellent quality and value for this model and Keychron really shows their care in presentation and design.

It was exactly what I needed
I’ve had this keyboard for just 3 weeks, and so far it’s still working great. It’s perfect for me: excellent sound, size, colorsâeverything is spot on. An incredible purchase, just as I expected.Even though I read terrible reviews about this keyboard, I wanted to give it a try because it was exactly what I needed. Its quality has nothing to envy compared to other mechanical keyboards.Iâll give you an update if any issues appear in the next couple of weeks or months.

Interesting keyboard., it is my second me chanical keyboard, first has logi mechini, no usb support as well as down grade windows such as windows 7. Keychron has an interesting forma factor, lightning was awesome. Easy to connect. Type c cable was premium, well covered. Even though it come with dtc courier they managed to deliver at my door. Actually I feel it too small. I primarily used it for professionals uses.

It is a great keyboard. Very light weight and thin. The keys feel nice. Easy to switch between devices, response time is around 1 second. However, I got a defected one. I tried to charge it on day one but I couldn’t see any light indicator. So I thought it was charging anyways. After 2 weeks of use, I realized that’s actually a led indicator next to the usb C port. and it was flashing red. I read the user manual again and found out that red flashing means battery low. The next thing happened is that my keyboard died. And now I can only use it with wire.
