Satechi Slim X3 Bluetooth Backlit Keyboard review

The Slim X3 is built for Mac owners who want an extended layout and backlighting, two things the base Apple Magic Keyboard does not offer. Satechi pairs macOS function keys with a full extended layout in a slim profile, and lets you set the backlight across ten brightness levels. It connects to multiple devices over Bluetooth and charges over USB-C. Satechi backs it with a 2 year warranty and 30 day returns on its US store. The product page is light on numbers: we could not find a published battery life figure or a device count, so compare the specs sheet before you buy if those matter. Satechi's own review section also includes verified buyers who report occasional Bluetooth dropouts, which is worth weighing against the MX Keys S at $30 more. At $89.99 it costs the same as the MX Keys Mini but adds a full extended layout.
