We've got one, and I like it.
It was bought after our plants were stolen from outside the front door.
It's very useful for 'answering the door' when you're out ("leave the parcel behind the plant in the porch" or "can't come to the door, I'm in the bath" - you can be anywhere!)
The motion zones are customised to avoid getting the yummie mummies on the school run, or next door going to work at silly o'clock.
No false alarms, and I've not knowingly missed anyone.
The battery needs charging about every 6 weeks (USB if not hard wired).
I've paired it with Alexa which gives it a much louder ring. The additional chime is a complete PITA.
