I previously purchased this item here, confirmed its functionality, and it worked without issue. However, I ended up not using it and have been storing it. The batteries were removed for storage, so there's no leakage. I'm also selling other baby items, and I'll offer a discount for combined purchases! ^ ^ The Babysense 5s accurately monitors a baby's movements. The previous owner used it for about 4 months, starting around September 2022. When the previous owner tried to remove the batteries for shipping, they didn't have the tool to remove the cover, so they used a flathead screwdriver, which caused a few scratches, but it doesn't affect its use. ^ ^ I will ship the item without batteries. It requires 4 AA batteries. - Brand: Babysense - Model: 5s - Included: User guide, sensors, stand - Function: Monitors baby's movements Thank you for looking.
