Works well. Setup experience for used card is a minor but easily overcome challenge.
Functionality is great, easy access over the network once configured.
Installation is very easy with a phillips screw driver; just open the port on the back of the UP and it slides in easily.
Be prepared, if you buy a used card you will likely need to use the serial interface to reset the IP settings; mine came hard-coded with an IP setup from a prior customer. Making a serial cable takes a few minutes and some jumper wires (APC uses an odd pin-out).
Either way, lots of documentation is available online so even a used card is an excellent value. Just be prepared to spend 30 minutes getting it reset and set up for your network.
Important: The reset button on the back only resets the password for 2 minutes; works fine, just remember to log in quickly. It also does NOT reset the TCP/IP settings, so again, serial interface cable to the rescue.
