Keychron K4 Wireless Mechanical Keyboard (UK ISO Layout) - Version 2

Really cool keyboard

I own a K1 Keyboard allready and I am very happy with it.
The K4 is maybe even better than the K1 :-)
The keys feeling is very soft, the design is great and it works without any problem on my laptop (macOS)

Looking forward to the K5.

Keychron K4 Wireless Keyboard

I am writing this review from my Keychron K4, and could not be happier with it. It is a solidly built product that feels much more premium than its modest price would suggest, and makes typing an actual enjoyable activity.

The best feature for me is the ability to switch between multiple bluetooth devices seamlessly. Using the Fn+1/2/3 keys you can pair and switch between up to three devices, and the transition is so fast that I can almost continue typing without interruption. For someone who has separate work and leisure machines, being able to use both with one keyboard on my desk is a real lifesaver. The instructions that come with the keyboard could be a little clearer on how to pair and manage bluetooth devices, but once they are connected it works perfectly.

Switching over to the UK layout keys was also nice and easy, and there a couple of different keycap tools provided, if you don't have any already. The keys themselves have a premium feel and weight - it will be difficult to go back to any other keyboard after using this one.

The only downside I have experience so far is that the battery life feels a little short - I usually have to charge it after about a week of bluetooth use. There is plenty of options to customise the backlighting under your keys however, so I'm sure if I wanted to make the battery last longer I could disable some or all of the lighting. In addition you can also run this keyboard just using a USB-C cable, so I was never left unable to use it even if the battery ran out.

Overall I am really impressed with the Keychron K4. I will definitely consider their products in the future, although it is hard to imagine needing to order a replacement any time soon.

Sturdy and versatile

The build quality of the board itself is excellent, nice and rigid with satisfyingly bright LEDs under the switches. It was easy to pair by BT and even easier to swap out all the switches to some more my taste (nothing wrong with the gateron blues but once i tried khale bronze I couldn't go back). Would definitely recommend

on a side note; I also purchased a set of keycaps when i purchased the board and did not notice that they didn't contain any ISO keys. I was told by CS that they have no plans to release any ISO keys for their keycap sets which was pretty upsetting; it's like 5 extra keys guys, surely you could sort that out!
