## What you’ll notice day to day

Pairing is straightforward and the keyboard can remember three devices, which makes switching between a phone, tablet and laptop quick. Typing feels compact, the keycaps are 14mm which suits brief emails and notes, though it can feel cramped for long documents. The PU leather cover protects the keyboard in a bag and gives a more professional look.

## Best use cases

It’s a good fit if you often draft short messages, edit spreadsheets on a tablet or use a mobile device for remote work. You’ll appreciate the battery life and the triple Bluetooth channels for multitasking. You may want to skip it if you rely on a full size layout or need a numeric keypad, as the compact format changes key positions and may disrupt habitual typing.

## Compatibility

The keyboard automatically recognises iOS, Android and Windows layouts, so it works with a wide range of devices including tablets and smartphones. Note that the compact layout may not replicate every desktop key exactly, according to the manufacturer.

## Included features

Built-in shortcut keys provide access to multimedia controls and quick actions via Fn combinations, and an auto-sleep mode helps preserve charge between uses. The on/off switch and Type-C charging make everyday use simple and practical.
