Thank you for viewing. Please be sure to read the profile. Purchased new in June 2025, I opened it and charged it, but never used it. Comes with the main unit, charging cord, instruction manual, and box. I chose this sensor because it has a function that vibrates when body movement stops. I bought it because it seems to make a difference in peace of mind at night. You can download an app on your smartphone to check the status and receive alarms. Color differences may occur depending on your monitor. Please refrain from purchasing if you are concerned. All items are sold as is, and are used. There may be odors, yellowing, minor scratches, and creases that I may not notice. Please refrain from purchasing if you are looking for perfection. Please understand that everything is used. Shipping will be via Yamato Takkyubin. Domestic shipping only. To reduce shipping costs, I will compress and use recycled materials for simple packaging. Please understand. No returns or refunds under any circumstances.
