# Upgrading to Wacom One Pen (CP-913)

## Overview

Devices that work with the Samsung S Pen also work with other UD EMR pens. In particular, these devices also work with the Wacom CP-913 pen.

* At the very least, you will have a backup pen.
* Max pressure - The CP-913 pen has a higher maximum pressure than the S Pen.
* IAF - The CP-913 has a similar IAF to the Samsung S Pen, and it may be slightly lower in the models I have tested. Keep in mind that individual units vary.

## Samsung Galaxy Tab S with the CP-913

Many Samsung Galaxy Tab users switch to the CP-913 because of its better pressure handling. It is worth trying if that matters to you.

## Key advantages of the CP-913 over the Samsung S Pen

* CP-913 units have a lower IAF, so less force is required for the pen to start drawing.
* CP-913 units have a higher maximum physical pressure. This makes it easier to control how pressure works with your strokes.

## Key differences between the CP-913 and the Samsung S Pen

* The S Pen has a rubber nib.
* The CP-913 uses a plastic nib. It may feel a little more slippery on the glass of a Samsung Tab S device.
