Babysmile Thank you for viewing. Purchased in 2025. I bought this because I was anxious about raising my first child. Just having this gave me peace of mind, made me feel much more at ease, and eased my anxiety. I used it for about 3 months. I will include the remaining batteries, but please let me know if you don't need them. 【Power Type】: Battery-powered 【Age Range】: Newborn ~ 24 months 【Sensor Sensitivity】: High sensitivity ※ It is generally clean, but please understand that there may be some minor scratches. Please purchase only if you understand that this is a used item. The box and instruction manual are not included. The items in the photos are all that are included. Operation has been confirmed.
