This device detects a baby's movements during sleep and alerts you with an alarm if no movement is detected. I purchased it new three years ago and used it a few times. Operation has been confirmed (as of October 2025). There is one scratch on the surface, but it's not very noticeable (see photo 2). The instruction manual is included, but it's slightly creased. Batteries are not included. The product box will be wrapped in a plastic bag for waterproofing, and a shipping label will be attached to it. Thank you for your understanding.
