Review: 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.
Review: 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.
