Nobody likes a trail of wires sprawling across their tidy desk, and wireless keyboards let you tuck those away. The best ones work with all your PCs, laptops and tablets (and even some media streamers, games consoles and NAS devices) thanks to rock-solid wireless connectivity via Bluetooth or 2.4GHz Wi-Fi (which requires a separate USB dongle). You can also choose models with backlighting for typing in darkened rooms.
If you're after a wireless keyboard for serious productivity and typing, it's worth paying extra for one with low-profile mechanical switches for snappier key presses. The SteelSeries Apex 3 is a great option, using whisper-quiet rubber dome membrane keys with excellent responsiveness and accuracy. Its surprisingly bright RGB backlight has a wraparound "halo" effect, which can be adjusted in the software to suit your colour preferences – although all that illumination does reduce battery life to about ten hours.
Another top pick is the Satechi Slim Wireless Keyboard, a Mac-style model with a two-zone arrow key row and a full number pad that's designed to save desk space. It's a bit pricey but it comes with a numpad and ergonomic mouse to make the most of its small form factor, plus it can connect to up to three different devices so you can switch with the press of a button – including copy-paste transfers. You can even bind the Fn keys to take screenshots or emoji shortcuts if you want.
