★★★★★It's good enough and cheap enough
I recommend this keyboard, as the price is unbeatable in this category. You will not find a better quality wireless keyboard, that has this many options for connectivity, for this cheap. Trust me, I looked for days online. I bought this keyboard as a temporary use case from my M5 Macbook Air docking setup. - Build quality is very good for an all plastic wireless keyboard - ZERO rattle from the keys, I shook it like crazy above my head and heard nothing. - Keys are nearly silent when typing. I wouldn't hesitate to use this in the same room as a light sleeper. - Keys require a little more pressure than I am use to. Sometimes I mistyped, as I am not use to having to completely bottom out a switch to complete the membrane circuit. I am very use to custom mechanical keyboards. - Keys feel overall ok. I am not impressed but I am not blown away. - Setup was incredibly easy using bluetooth. 1 switch and a couple button presses later and you are off to the races. - Keyboard arrived fully charged out of the box - Wireless adapter is easily accessible and housed on the underside of the keyboard. - Comes with charging cable. - There isn't much for lighting on the keyboard as it just has 3 small LED's on the top right for connectivity and capslock. - I'm sure battery life is impressive but I haven't had it long enough to discover it capabilities.

★★★★★A well-executed keyboard provided that the layout is a good fit for you
There are two major things that you need to keep in mind when looking at the B31. First: this is not a mechanical keyboard like many of Keychron's other offerings. The price and experience reflect that. It is a solid scissor-switch keyboard, but don't expect magic. Second: 75% is not the most compact layout out there, but it *is* small . Some keys are going to be in places that you may not be familiar with if this is your first < 100% (or even TKL) keyboard, and even if you've used them before different manufacturers sometimes play with the specifics. With that out of the way: the B31 is a well-built and well-executed keyboard. It feels a lot nicer than the "standard" office/home keyboards you'll find out there, particularly with regard to its chassis and switches. Tri-mode connectivity (USB, BT, and 2.4GHz) can be *very* handy depending on your needs, and both the dongle (in its recessed slot) and USB-C port are easy to access quickly if you need to move things around. The big elephant in the room is the scissor-switch style. These switches are typically found in laptop keyboards, and have two fairly general qualities: they're quiet, and they're low-profile. You're not going to get anything remotely approaching a defined "click" when pressing these keys, even if you bottom them out. Things feel very mushy compared to a mechanical keyboard, but about as you'd expect if you work with laptop keyboards and/or rubber dome desktop keyboards. The shallow key travel makes it a bit easier than I'd like to hit the wrong key, but all things considered that's not Keychron's fault-- I'm just used to higher keycaps. The keyboard has adjustable feet that have two settings, so you have three choices of angle total. Generally speaking, the keys feel as good as you'd expect, but I do hear a decent amount of squeaking (particularly when hitting larger keys, like [space]). One thing that dramatically recommends this keyboard over other cheap options is its versatility. Yes, there are many keyboards that can swap between a Windows/Mac layout, but the B31 can also be programmed using Keychron's web-based app (so long as you have your keyboard connected via the 2.4GHz dongle or USB-C; the app only works with Chromium-based browsers due to the HCI protocol involved). Keychron's Launcher app is easy to access and is quite snappy. It lets you remap keys, program macros, and generally fiddle around with the nuts and bolts of your keyboard. That's a big benefit for a key-limited board like this one, especially if you're finding certain keys awkward in terms of their position (or miss specific keys from a larger layout). Given that the keycaps are all about the same size, I'm considering pulling up the caps for the four navigation keys on the right-hand side to have [pgup] and [pgdn] where the [home] and [end] keys are, but I've yet to decide there. Wireless pairing functionality and status lights are clear and easy to read. Another plus for Keychron, who keep things very simple. On the balance, this is a great value at its price point and could quite readily serve as a main keyboard if you can get by on the 75% layout. As a backup or mobile keyboard it's excellent due to its low profile and light weight. Give it a go-- as long as you know what you're buying.

★★★★★Good over all - with quirks
Keyboard works well, but has weird ghosting. Where a key will be stick while not typing.

★★★★★Nice 75% wireless keyboard; lots of customization, not 100% silent but close
This keyboard is a somewhat lightweight wireless keyboard with both Bluetooth and 2.4GHz pairing options. It has a USB wireless receiver which can be used if you do not have a Bluetooth capable device. You can also use it as a wired keyboard via a USB-C cable, which is also used to configure the keyboard via the Keychron launcher. It has up to a 1k polling rate via cable, and the typical Keychron configuration for keys, layers, macros, and so on. It also has a sleep timeout setting when using wirelessly, which is 2 hours by default. It can be used for Windows, Mac, or any other Bluetooth device supporting a keyboard, and has dual-labeled keys for both Windows and Mac use. I like the blue color palate as well. The keyboard is advertised as "silent", which is mostly accurate. There is a very quiet sound that I would describe as light mechanical shuffling upon rapidly pressing and releasing keys when typing. If you deliberately push one key all the way in and let it go, it is indeed pretty much silent. The keys feel a tiny bit mushy, but the are tolerable to type on and are similar to some laptop keyboards. They don't have very much travel, but I am able to type at normal speed with them without issue. Of course, it is a 75% keyboard so it is missing a numpad and some various function keys as a result. The keyboard has no backlight, which obviously serves to improve battery life. As a result, there is a Caps Lock LED which comes on if Caps Lock is enabled. This light will stay on until the keyboard sleeps - I set the sleep duration to 5 minutes to test this. If you leave Caps Lock on, it may reduce battery life a bit as a result. There are also status lights for the wireless connection and the battery/charging. As shown on the quick start guide, the keyboard has three Bluetooth "channels" which let you connect to and switch between multiple devices. When turning the keyboard on for the first time, you have to hold fn + 1 (or 2 or 3) to enter Bluetooth pairing mode. Channel 4 is for the 2.4GHz receiver. The keyboard reports battery life via Bluetooth so that you can see the percentage remaining, which is nice. It charged up fairly quickly when I had it connected via cable. After going to sleep, it reconnected within about two seconds when I pressed a key, which is reasonable - but may throw you off if you expect to be able to type immediately at any time. I also like that it has tilt legs. Overall, this is a pretty decent small wireless keyboard for the money, especially considering the customization options. I plan to use it for a Home Theater PC where I don't often need a keyboard, but when I do it's handy to have a Bluetooth one that I can grab really quick and use as needed.

★★★★★Neither Silent nor Backlit, But Does Work.
I got this keyboard to use as an external keyboard for my 11” iPad Pro. I am a fan of this size (75%) keyboard. I don’t need a number pad but I do like full-size key caps. Let me begin by pointing out that iOS devices are not supported, according to the chart on the seller’s page. Nonetheless, I connected to my tablet via bluetooth without difficulty and it works fine. I only use it for text entry and have no idea how switching the keys to multimedia mode would work. The keyboard is not silent, as promised. The keys make a bit more noise than my laptop keys. That bit of mechanical noise is noticeable in the quiet of a research library reading room. I am not a keyboard connoisseur and my work does not require rapid typing speeds. I do find, though, that the shape of the key caps makes the top of the keys somewhat smaller than the bottom (a design choice I do not understand). My fingers often fall into the open space between the keys and that leads to errors. Please note that the keys are not backlit. The device does not come with a detailed set of instructions. There is a bare-bones manual of sorts online. There is no power button and I could not figure out how to make the keyboard sleep to conserve battery. There seems to be some online confusion about that function. The keystroke combinations to display battery charging level do not produce the promised result. They only make the bluetooth indicator light flash briefly. I tested this keyboard on my Windows desktop unit, my Mac laptop, and my iPad. It worked in each case. After a good bit of use I am going to keep searching for a keyboard that is reasonably priced but with a little more quality.
