I purchased this as a gift, but as the recipient already had one, I've kept this new and unused. It's been stored for about three months. I didn't notice it because it was packaged, but there's a small scratch on the box. Please check the photos. Retail price: 8580 yen ★ Equipped with a heart rate sensor! It vibrates at a rhythm tailored to the individual, and by playing melodies at a matching speed, it creates an environment conducive to the baby's sleep. ※ It cannot measure numerical values. ★ Uses a fluctuating rhythm! By gradually slowing down the vibrations and melodies, and skillfully shifting the rhythm at mathematically calculated timings (1/f fluctuation), it plays vibrations and melodies that match each individual. ★ Built-in sounds: intrauterine sounds, natural sounds (2 types), melodies (5 songs). Features a 30-minute auto-off function, and the stuffed animal is hand-washable. ※ The heart rate sensor unit is not waterproof.
