I purchased this intending to use it after my baby was born, but I ended up being too busy and never used it, and the time I needed it passed. I would like to give it to someone who needs it. It is new and unused. It has been stored at home, so the outer box has some dents as shown in the photos, but I think there are no problems with the product itself. Please purchase only if you understand this. 【Product Description】 ・Placed under the baby bed mattress to detect and notify of the baby's movements. ・Alerts with an alarm if movement, including breathing, stops. ・For monitoring while parents are sleeping. ※This is not a device used for the prevention of Sudden Infant Death Syndrome (SIDS) or for the evaluation of sleep disorders (such as sleep apnea). The baby alarm uses a high-performance sensor built into the panel to detect the infant's movements, including breathing. It accurately detects the infant's movements during sleep, and if no movement is detected for 20 seconds, it alerts with an alarm. It prepares for emergencies such as SIDS, falls, and suffocation. - Brand: BabySmile - Model: E-201 - Product Name: Baby Alarm - Accessories: Cable, sensor unit, strap, box, instruction manual and other documents (same set as when purchased) Power supply: 3 AA alkaline batteries Please prepare the batteries yourself.
