Does it work with a smart TV?

It pairs over Bluetooth with devices that accept Bluetooth keyboards, including many smart TVs and streaming boxes. Check that your TV supports Bluetooth keyboard pairing first.

Is there a number pad?

No. It uses a compact QWERTY layout without a number pad, so number-heavy work is slower.

Does it need a USB receiver?

No. It connects over Bluetooth, so no dongle is needed on devices with Bluetooth.

Can I use it with a phone or tablet?

Yes, it pairs with Bluetooth phones and tablets that support external keyboards. The touchpad works as a pointer on most of them.

What comes in the box?

Expect the keyboard and a charging or USB cable, depending on the version. A Bluetooth host device is required, since no receiver is included.

Is it worth it over a separate keyboard and mouse?

It replaces two devices with one and needs no flat surface for a mouse, which suits couch and lap use. A separate keyboard and mouse give better key feel and pointer precision if you type or point a lot.
