Babysmile Baby Alarm Movement Sensor - Brand: Babysmile - Type: Baby Alarm Movement Sensor - Color: White - Retail Price: ¥9,800 I purchased this used in late September 2025, but my child doesn't sleep in the baby bed, so I hardly used it and put it back in the box immediately. The previous owner used it for about two months, starting in June 2025. I think it's in very good condition. No pets, no smokers.
