Thank you for viewing. Purchased in May 2024. I was worried about SIDS (Sudden Infant Death Syndrome) because my baby was sleeping alone, so I took this with me on trips and when visiting family until my baby was one year old. I hesitated to buy it because it was expensive, but just having this allowed me to sleep soundly at night from the newborn stage. It was expensive, but it's truly the best baby item I'm glad I bought.:*☆ Once set up, it was rarely moved, and the main unit was fixed to the baby bed, so it's in clean condition. ~Recommended Points~ ★ Approved as a general medical device in Japan, the EU, the UK, Australia, and Israel, and has a proven track record of being used in hospitals, so it's reliable. ★ Only the main unit and two sensor panels, making it easy to set up and carry. ★ Battery-powered and doesn't use radio waves, so operation is extremely stable. ★ Doesn't touch the baby's skin, so there's no risk of injury. Please feel free to contact me if you have any questions or concerns about using it.:*☆ Operation has been confirmed.
