※ The batteries have been replaced with new ones for this listing, so it's ready to use immediately. Thank you for viewing. I purchased this new and used it to prevent my child from sleeping face down. It connects to a smartphone and alerts you immediately with an alarm if the baby rolls over, which was very helpful. Also, you can see the temperature, so it was helpful to check in the winter to make sure the baby wasn't getting too hot with layers of clothing and blankets. The print is slightly faded, but I have confirmed that the functions work without any problems. My child is now over one and a half years old, so I will pass it on to someone who needs it. Please feel free to ask if you have any questions.
