Slim X3 Bluetooth Backlit Keyboard Review: Compact Typing for Mac and PC

Finding the perfect keyboard for a multi-device workspace can be a challenge, especially when you need something that works seamlessly with both Mac and PC. The Slim X3 Bluetooth Backlit Keyboard promises a compact, wireless solution with backlighting and broad compatibility. In this review, we'll put the Slim X3 through its paces to see if it lives up to the hype.

We'll examine its design, typing feel, connectivity options, battery life, and how it compares to other Satechi keyboards like the SM1 Slim Mechanical Backlit Bluetooth Keyboard. Whether you're a writer, programmer, or just someone who wants a clutter-free desk, read on to see if the Slim X3 is the right keyboard for you.

Design and Build Quality

The Slim X3 sports an ultra-slim aluminum chassis that matches the aesthetic of Apple's Mac lineup and modern PCs. Its compact layout omits the number pad, saving desk space while retaining essential keys. The backlighting offers multiple brightness levels, making it easy to type in low-light conditions. The scissor-switch keys provide a stable, quiet typing experience with good tactile feedback.

The keyboard is available in space gray and silver, blending into both Mac and PC setups. The build quality is solid, with a premium feel that belies its affordable price. The included USB-C charging cable is a nice touch, allowing you to charge via your computer or any USB-C power adapter.

• Tip: Use the function key combo to adjust backlight brightness on the fly.

Typing Experience and Performance

Typing on the Slim X3 is a pleasure thanks to its well-spaced keys and responsive scissor switches. The key travel is adequate for a slim keyboard, providing enough feedback for touch typists. The backlighting is uniform and bright, with three adjustable levels plus an off mode. The keyboard connects via Bluetooth 5.0, ensuring a stable, low-latency connection up to 30 feet.

Battery life is impressive, lasting up to 80 hours with backlighting on and even longer with it off. The keyboard automatically enters sleep mode to conserve power. Pairing with multiple devices is easy, and you can switch between them with a dedicated key. We tested it with a MacBook Pro and a Windows desktop, and both recognized it instantly without any driver issues.

• Tip: Use the dedicated media keys to control music and volume without reaching for your computer.

Connectivity and Compatibility

The Slim X3 uses Bluetooth 5.0 to connect to up to three devices simultaneously. Switching between them is as simple as pressing a key. It works out of the box with macOS, Windows, iOS, and Android. The keyboard also includes a USB-C port for charging, and you can use it wired if you prefer. There is no dongle required, which is great for travel.

For users who need a mechanical feel, Satechi offers the SM1 Slim Mechanical Backlit Bluetooth Keyboard, which features mechanical switches and a similar compact design. However, the Slim X3 is quieter and more portable, making it ideal for shared workspaces or coffee shops.

• Tip: Keep the USB-C cable handy for charging while you type – the keyboard works perfectly in wired mode.

Comparison with Other Satechi Keyboards

Satechi's keyboard lineup includes several options. The SM1 Slim Mechanical Backlit Bluetooth Keyboard offers a mechanical typing experience with hot-swappable switches, but it's slightly thicker and heavier. The Slim W1 and Slim W3 are wired alternatives that lack Bluetooth but are even slimmer. The Slim X3 strikes a balance between portability, wireless freedom, and backlighting.

If you prioritize battery life and low-profile keys, the Slim X3 is the better choice. For mechanical enthusiasts, the SM1 is worth considering. Both keyboards support Mac and PC layouts, with keycaps that include both macOS and Windows modifiers.

The Slim X3 Bluetooth Backlit Keyboard is a versatile, well-built keyboard that excels at multi-device typing. Its compact size, excellent battery life, and backlighting make it a top choice for Mac and PC users alike. If you're looking for a reliable wireless keyboard that won't clutter your desk, the Slim X3 deserves serious consideration. Pair it with a Satechi USB-C Hub for a complete workspace upgrade.
