What is the benefit of this over, for example, an iPhone hotspot?
An iPhone can't bridge a wifi network. So you need something like a travel router to share a wifi connection.
chromecast - godsend on long hotel stays. need to dial in through my home (wireguard) so no license issues with streamers and once I connect my GL.iNet GL-MT300N-V2 to hotel wifi instant bubble of safe wifi for all my devices! weighs nothing, been using for 8 years rock solid.
If you’re using a VPN: iPhone won’t route hotspot clients over the VPN, so you need to set up VPN on all clients.
You can control it from the ground up, including installing alternate firmware. You can also use VPNs etc.
Husband can go pick up food order and baby cam still accessible from wife’s phone.
Run one wireguard server in your home and one client instance on this router and now all of your devices can share the same residential VPN connection. No fraud blocks or extra verifications from your banking apps, no million suspicious login detected from all your social accounts, use your home netflix account, etc. All without your individual devices running a VPN app.
