I would recommend moving up your price-point (if at all possible) and buy something slightly more capable that will last, potentially, longer.
Protectli [0] and Qotom [1] are popular among the OPNsense[2] / PFsense[3] / Untangle[4] firewall distros with respect to small form factor devices.
If all you want is a cheap "router" with a bare bones feature set for Internet edge routing I'd recommend a Ubiquiti EdgeRouter X [5]. At $59 it's the best piece of hardware you're likely to get for the money with total control and less big-brother.
If you can't find one email me at my HN username at counterbrea dot ch. I have a few different unused EdgeRouters I could send you for the cost of shipping.
