Great little alarm!
Great little alarm, works as expected. If you are installing yourself, make sure you put it on a different electrical circuit than your radon fan. There is no battery backup in this unit so if your radon fan circuit breaker trips and this unit loses power also, it will not alarm. Kind of wish it had a backup battery so I didn't have to run new electrical to it, but I'm sure that would increase the price of the unit so the tradeoff is ok with me.

Perfect Little Alarm
We use these in all of our commercial vapor mitigation projects (chemical vapor intrusion sites). Very simple to install and they work great. The shrieking loud sound will not be ignored. I can't speak to longevity because our oldest system is 2 years old. We post a laminated sheet giving instructions to building occupants on what to do if the alarm in sounding. This is a much better system than the standard manometer stuck to a pipe, like the ones that most radon contractors use.

Simple install, works perfectly, loud alarm
I installed this in addition to the J hook indicators typically installed. Drilled a hole in the PVC pipe, stuck the hose in, plugged it in and good to go. I tested it and it works as designed. The alarm is loud enough to hear upstairs since we rarely go in the basement so I feel comfortable I’ll know if/when the radon fan goes out.

works as expected
easy to install, works better than the visual alarm that one might ignore or forget. the alarm is audible and appears to work under various tests.
