Sense-U Baby Monitor Used from approximately November 2024 to March 2025. It has been stored since then. It works without any problems. The battery is low and needs to be replaced. Original price was around 14,000 yen. There is no box or instruction manual. Please be aware of this. It is in good condition with no noticeable stains or scratches. As a worrier, this really helped me. I am selling it because I no longer use it as my child has grown.
