Keychron K5 Max Ultra-Slim Wireless Custom Mechanical Keyboard, QMK/VIA Programmable 3-Mode Bluetooth/2.4 GHz/Wired with RGB Backlight Low Profile Gateron Brown Switch, PBT Keycaps for Mac Win Linux

Nicely constructed. Good quality.

I work from home and I wanted a quiet keyboard to meet many of my needs. This keyboard has surpassed them all! It is low profile, full size, quiet keys, lights up with different options, works amazingly with my Macbook Pro, has fun customizable keys, is not made out of cheap plastic, and It is worth every penny.

Absolutely wonderful keyboard! Types really well. Will be buying another one for home and office.

The keyboard arrived with a visibly misaligned “H” key that proved to be a broken switch underneath. The “H” key is unuseable. I emailed Keychron product support immediately, who advised that someone would be in touch shortly, but it has now been close to a week with no update on a solution. Very poor customer service on a product I was excited to purchase.

Writing a review with great typing feel of Keychron K5 Max keyboard brown switch. I did some research before purchase this one. Excellent feel while typing, low noise, many options on connects to PC, build quality is super, This is my first keychron keyboard after using logitech for long time.

I just got in my Keychron K5 Max and love it. I was trying to decided between spending the money on another Logitech MX Mechanical or the Keychron. If you are trying to decided which keyboard to get, get the Keychron!

This is like my 3rd purchase, they make great physical keyboards but they all have bad firmware, after just a few months they tend to double type or switch characters, its a common reoccurring issue

Maybe it's just because this is my first mechanical keyboard, and the low profile fits me better than I've found with standard-sized mechanical KBs, but I generally like this keyboard. It's got a pretty solid build quality and it's weighty but not heavy. I like the multiple types of connections I have available to me, though I'm admittedly using it wired for primary computer. The QMK/VIA aspect is very handy and I've already seen at least one firmware update, which included additional features, since I bought it.Now, for the downsides: Maybe you can overlook each of them as small, but all of them together had me really debating whether I'd return it. The North-facing RGB is almost completely obscured by the keys, so it's almost pointless to us it unless you're in a very dark room. The RGB really drains the battery as well, even in splash mode (only lighting when you type), which is why I'm keeping mine wired for now. There are virtually NO replacement keycaps available for those who would want transparent/translucent keys to see the RGB more clearly, and there are very few alternative symbol/function caps that come with the board. You'd think there would be more considering how highly customizable this thing is (and that it's intended for both Mac and Win).Lastly, the REALLY frustrating bit: The spacebar is TOO easy to mistakenly hit--over and over and over again--and there's no lip below it to rest your thumbs like I had with my former keyboard. I bought a wrist rest to give my thumbs a spot to rest, hoping that would help. It did, but only slightly. I originally went with the brown switches (and hotswappable, just in case) over blue or red because I wanted feedback and some resistance without clickiness. That was good, but I'd heard the banana switches were better and the Max version doesn't offer them preinstalled. I ended up buying a few banana switches because I wanted more resistance on the spacebar without it being clicky and the low profile only allowed for the 4 choices of Gateron switches (maybe others are compatible, but I went with the sure thing). I really liked the added resistance and only slightly clickier sound. So, I bought enough to swap out all the keys. IT FEELS WONDERFUL, now... except for the spacebar, still. So, I now have mine rigged up with all banana and a single blue switch for the spacebar. It's helped a lot with regard to reducing mistaken spaces, but it's still not perfect and it sounds a bit weird that there's a loud click only when I'm hitting space. I've gotten used to it, but I can't say if my coworkers have or not.All in all, I'd like to see a LOT of improvements from Keychron's low-profile 100% option, but this was a relatively low cost start compared to others out there and core functionality is generally acceptable.
