I used this at the clinic where I gave birth. 【Ships immediately! ! Instant purchase OK!】 ⭐︎ I will include 4 new batteries, so you can use it as soon as it arrives ◎ I used it when my baby was a newborn and stored it for a while. The power turns on. The alarm sound also worked. Please understand that this is a used item before purchasing. I felt relieved during the newborn period when I was worried about whether my baby was breathing.
