This is a BabySense Home movement sensor. Purchased new around January 2025 at the list price. List price: 27,071 yen Used as a SIDS (Sudden Infant Death Syndrome) countermeasure. This product is often used in maternity hospitals, and thanks to it, I was able to sleep peacefully. I used it for about six months, but I gradually stopped using it, so I am selling it. The operation has been confirmed at the time of listing. I think it is a beautiful item with no noticeable scratches. The instruction manual and installation parts are all included. No smokers, no pets. To prevent product substitution, please refrain from returns and exchanges. Please purchase only if you understand that this is a used item.
