【Tested and Working】Infant movement sensor. Purchased in March 2025, but my child rarely slept, so I had to wake up many times, and the sensor was hardly used. Used about 4 or 5 times during the newborn period. All accessories are included. I plan to take it out of the box and pack it. Please understand. The batteries that came with the purchase are already installed, so you can use it immediately after purchase. Thank you for your consideration. Instant purchase is OK ⭕️
