BabySmile Baby Alarm E-202 Purchased in February 2025 and used for about a month, only at night. There are no scratches, and I have confirmed that the sensor operation lamp lights up without any problems when the power is turned on. This is a home infant movement sensor that detects body movements, including the breathing of infants. - Brand: BabySmile - Model: E-202 - Function: Baby Alarm - Included Items: Instruction manual - Target Age: From 0 months old
