FAQ

The Bluetooth range is up to 10 meters or 30 feet.

The Slim X3 keyboard allows you to pair with up to three devices. You can switch between them by pressing the corresponding Bluetooth button (1, 2, or 3) on the keyboard. Be sure to pre-assign your devices to each desired Bluetooth button.

For Mac users, you can follow the steps outlined in the guide Enter characters with accent marks on Mac.
For Windows, this function isn’t supported natively. ALT Codes may work, but this hasn’t been fully tested as our keyboards were primarily designed for Apple devices.

Our keyboards do not support the battery percentage feature on macOS similar to the Apple Magic Keyboard or Mouse. macOS may display ~60% even when fully charged.

Instead, the keyboard notifies you when low on battery via the power LED indicator at the top right:

The LED light will blink red when it has reached below 15%.

    Best Keyboard I've ever used...

    This is an awesome keyboard. I was using a Dell keyboard. It was ok but I found I made a lot of mistakes, catching the odd key here and there. This doesn't happen with the Slim EX3. I'm a convert
