Design
Design of the keyboard looks good. Two colours available are black and white. The white one should pair well with Mac products. The keys have symbols for Windows and Mac.
The rubber feet have good grip on the table.
The keyboard is thin, compact and do not take up much space on the table.
The 75% layout with 79 keys is compact. Fn key is located on the left side, between the L-Ctrl and L-Option/WinKey, where I prefer. R-Option for Mac works as R-Option. The function key shortcuts are useful. Location of the keys are very logical.
Circular keys are used for the B3 Pro, B4 Pro and B5 Pro compared to the square keys on other B series keyboard.
The keys use scissor switch mechanism. Typing experience is great. Keys have good feedback and typing is swift, quiet.
At the top are the switches for different connections, Mac and Windows, USB-C charging port and the reset button.
Keyboard can be paired to three devices with Bluetooth 5.2, supports 2.4Ghz connection and has wired mode. Switching between the different connections is convenient with the Fn + 1, 2, 3, 4 keyboard shortcut.
Keyboard can still be used when it's charging. Battery life is up to 300 hours.
The keyboard can be customised through a web browser using the Keychron Launcher web app. No driver installation is needed to configure the mouse. This mouse can be configured with computer systems that are locked down by IT departments.
Despite how thin the keyboard is, there's still space to store the 2.4Ghz wireless adapter.
Conclusion
The Keychron B3 Pro is a beautiful compact wireless keyboard that provides a good typing experience. The price is very reasonable so this keyboard provides great value for money.
The only one downside is there's no backlight.
Availability
The Keychron B series keyboards are available from Keychron online store.
