KeychronK3 Max QMK/VIA Custom Ultra-Slim Wireless Mechanical Keyboard, Hot-swappable 2.4 GHz/Bluetooth/Wired 3-Mode 75% Layout Programmable RGB Backlit Red Switch Gaming Keyboard for Mac Windows

The appeal of a thin mechanical keyboard that I could potentially use with one hand when my other was occupied was just too great. As it turns out, the feel of the low-profile Gateron Browns on this keyboard is even better than on my daily driver, a split keyboard which uses Cherry MX Reds. Now I'm going to have to revisit those as well! I love that this keyboard has a switch for wired/wireless/off, and easily tucks away on top of my mid-tower just under the desk. If I have one gripe, it's that the keycaps aren't shine-through. But that's easily solved given how customizable this keyboard is!

This keyboard is the most frustrating thing I've bought. Several months into owning it, it started doing this weird thing where, if the RGB lights turned on, all of the keys on the first row would randomly activate over and over again causing all sorts of chaos on the screen (alt-space, ctrl-left, etc...). I got it replaced under warranty, and the next one started doing the exact same thing several months into it. None of this will happen if the RGB is off, which is a bummer in itself (but at least it's functional), but the RGB will turn on randomly and then the chaos starts again. I cannot trust this keyboard, and therefore it is useless to me.

Works with PS5 through the dongle. No significant input lag has been noticed

Sometimes the keyboard would disconnect even at charge.

Doesn’t hold up. Doubles my keystrokes. I liked how it looked and felt but can’t even perform the basic function correctly. Disappointed

As many others have noted, this keyboard will begin randomly typing on the bottom row. This started happening about 3 months into owning the keyboard. At first it was only an issue when the RGB was turned on, but it slowly spread into a permanent issue. The keyboard is now completely unusable.Tearing into the board, there does not appear to be any visible damage to any of the components. It is likely due to either poor firmware or a bad PCB.Keychron should be ashamed of themselves for pushing out faulty products.

I love it, it's my first mechanical keyboard. I love how compact it is, it is not noisy and it worked with my MacBook Pro.Update: After a month the backspace key stopped working properly, now it gets pressed multiple times, which makes difficult to type. And this very expensive keyboard does not come with any spare switch, so I had to swap the faulty one with one from a key I don't use often. I will not buy this brand ever.

The media could not be loaded. This is my second unit after exchanging the first one with Amazon because it had the same issue. Basically if you are using the keyboard with a wired connection, toggling the RGB to on causes the entire bottom row of keys to press randomly. There is no way around this and flashing the most recent firmware, pushing the reset button, or using a different computer/cable/USB port does not fix the issue. Honestly such a shame because I bought custom keycaps for this board and am not convinced at all that another exchange will fix the issue.
