One worked, one faulty
Ordered two of these microphones (luckily). One of the units was faulty (did not pick up any audio at all), and on inspection the microphone chip was not squarely seated on the PCB. Other working item is as expected. Awarding 3 stars as a neutral rating given half my order was faulty and will be returned.
