Purchased in December 2024 and used for about six months. Operation has been confirmed, with no issues. The main unit was kept under a mat the whole time, so it's clean with no scratches or stains. The rental baby bed return date is approaching, and we'll be changing to a sleeping arrangement where we sleep together in a bed, so I'm passing the sensor on to someone else. I bought this because it was used in the maternity hospital. I slept soundly at night for about six months! The batteries will be included when shipped. There is no box, so it will be wrapped in bubble wrap. The instruction manual is included and will be sent along with it. - Brand: BabySmile - Model: E-201 - Set Contents: Control unit, sensor, instruction manual, strap - Features: Infant movement sensor Thank you for your consideration!!
