Baby monitor with a sensor to monitor a baby's body temperature and movement. It has a base station that connects via Wi-Fi, so you can use the app to link with your spouse, etc., and check the baby's movements, sleeping position, room temperature, etc., even when you're away from home. The sensor can also be used on its own. There is a fold on the back of the instruction manual and some slight dirt on the sensor. I bought it new and used it for about two and a half years, but the base station broke, so I bought a replacement on Mercari. Also, the main part of the power adapter is not the original one. I will include it as it worked without any problems. If you don't mind the batteries being partially used, I can ship it with them inserted, so please let me know. *I am decluttering in preparation for a move and plan to remove the listing at the end of February. I will wrap it in bubble wrap and a bag, but I will likely use paper bags and cardboard boxes I have at home for the outer packaging, so please be aware of that. *Please feel free to discuss shipping methods and discounts. - Model Name: Sense-U Baby Monitor 3 - Included items: Charger, sensor, instruction manual - Function: Monitors baby's body temperature and movement - Color: White - Brand Name: Sense-U Thank you for looking.
