Well, I have had 0 outages exceeding 4 or so hours at home in the past 5+ years. But let's forget about the long outages, the bigger issue is that I will often get shorter outages on my phone or other devices. For whatever reason, the endpoint I am connected to will have gotten slow/gone down, and I'll have to disconnect and then reconnect. That's annoying. I want this process to happen automatically, perhaps with the router connecting to 2-3 endpoints per VPN service at a time, and 3-4 different VPN services, so that it all happens transparently and I don't ever have to tinker with it because something is slow. I mean, I've had to tinker with my router at home exactly 0 times during the past 3-6 months. When I'm in China, I usually spend a ridiculous amount of time diagnosing/fixing or just working around (having to switch endpoints) network issues. I'll wake up and my phone/laptop had been connected to ExpressVPN or VPN.ac or even Shadowsocks, all night, and the tunnel will be down, or extremely slow. I'll try watching a Youtube video and the phone will pause the video and start buffering, something that almost never happens at home. And then I'll wonder: can I get better throughput by using Hong Kong 4 instead of Japan 2? What about Los Angeles or San Francisco? Can I get better throughput by switching from VPN.ac to Express or to Shadowsocks? I want a router that will do all of this probing/testing in the background so that I don't have to.

And also, my wife finds it annoying to have to use browser plugins to download Chinese content that is only available inside of China, hence the last bullet point requirement.
