Excellent condition. This thing was my best friend when I was pregnant with my girl! Easy to use, multiple display types and a rechargeable battery. Great to have for in between visits and to listen in on your baby! This device is not intended to diagnose medical conditions, always consult your doctor with questions about your baby’s heartbeat. **Video added is a demo using my own heartbeat, just so you get an idea of how it works** Comes with lithium rechargeable battery and charging cable.
