The main thing to know
It has no rest mode, so unlike a hibernation-capable monitor it keeps transmitting all night even when the room is silent, though the analog signal it sends is very low to begin with.
This is an audio monitor with no camera, so if seeing your baby on a screen matters to you, this is not the one.
Skip this if you...
You want the monitor to go silent on the airwaves when the room is quiet
You want to see your baby on a video screen
You need a model that is reliably in stock
You want to see your baby on a video screen
You specifically want a published, independent emission measurement
You want breathing or vitals tracking
Neither of these quite what you're looking for?
