Review: Great Gateway, OpenWRT is a big plus - Got this as a fail over gateway for my network for the my main ISP dies. Setup is easy, the web UI from the factory is pretty intuitive, though I quickly flashed vanilla OpenWRT onto it. Works with Google Fi (T-Mobile) with no issues. The default firmware is based on OpenWRT, and it has an additional simplified UI on top (you can still access the vanilla OpenWRT though). I opted to flash vanilla OpenWRT, and this works just as well. The firmware update process is safe and has a feature to install firmware even if the device can't boot. The manufacturer has tools available to build new firmware too on GitHub, so it's all pretty transparent. Hardware is solid too. Haven't ran this long, so can't comment on stability but the case and antennas are all good. Easy to get into the case, so in theory you might be able to replace the module, though I've never tried it nor do I know if it's actually supported. Overall, the hardware seems really solid and the open source firmware is a huge plus. The factory firmware seems open and solid, but I preferred getting into things a bit lower, so I went with something else. The fact that the factory firmware uses open source tools and you can put your own on (the manufacturer's site tells you how) is pretty cool.
Review: Works great! - Installed in a remote part of a workshop, I used the external antennas mounted on some acrylic to point at the nearest cell tower. 10/10 Setup was easy, configuring the cell connection took minutes. If you need a long lasting cell connection this is likely your Best Buy for the money spent.
