I set one up for the first time a few weeks back. The Web UI would sometimes time out my session after less than a minute, and then many of the sidebar buttons would be duplicated. Choosing a "template" option for how the WiFi/LTE is used would appear to take effect, but be ignored. There was no option to enter a password for the 5GHz radio, it simply remained open. It stopped responding and had to be factory reset. This was all over a stable wired Ethernet with a browser config that allows scripts, cookies etc, and before any work I'd upgraded its firmware and performed a factory reset. I too was a bit horrified.
