First of all: this is NOT to use when a person is in the seat!
I only recommend using this one when having an object, like a backpack or such, in the car seat and that triggers the chime.
Or if your chime goes on like mine: all the time... Even when there is nothing in the seat at all. So I use this all the time with an empty seat.
