This is the part that sold me:

“Multi-WAN network toolkit — connect up to 5 uplinks. Configure dynamic routing, failover, load balancing, and firewall rules. Use it simultaneously as a Wi‑Fi hotspot and client. Tunnel traffic through a VPN and multiple gateways. ”

I haven’t been able to find an off the shelf device that provides this. I travel a fair bit and when sitting in an airport mobile hotspotting is often unusably slow. If I can use this to securely connect to public unencrypted wifi, it will make travelling that little bit easier
