Mine is two years old and still working. This <https://www.airgradient.com/shop/#!/Open-Air-Outdoor-Monitor-O-1PST-Kit/p/616991252> one. Other than the time the firmware upgrade <https://forum.airgradient.com/t/help-us-with-the-wi-fi-issue-of-firmware-3-6-0/5942> had issues, it has been good. Seems to line up with the purple air monitors in the area.
You can see it on the map <https://www.airgradient.com/map?zoom=15&long=-121.37&lat=38.73&meas=ug_m3&wind_layer=false&fires_layer=false&map_theme=light&org=ag&embedded=false&sidebar=1&loc=723> and I have it in Home Assistant. I built a several sensors using pm5003 sensors from aliexpress and some plans from here <https://sensor.community/en/sensors/> (which seem to be gone). None of them lasted and I assume the pm5003 units were fake.
