Sonoline B Baby Activity & Heartbeat Monitor
- Product Review (submitted on November 4, 2016):
- Very nice to hear the baby's heartbeat.... But the heart rate number was all over the place.... It would be start at 135 and keep dropping like a count down 134,133,132,130....all the way down.... So I'm not sure how accurate that part it... But I could hear the heartbeat loud and clear... Had very fast shipping.
