Sonoline B Baby Activity & Heartbeat Monitor
- Product Review (submitted on March 25, 2019):
- I dropped a star because the numeric reading is nowhere close to accurate. The numbers read 109+ before the probe has ever been placed- and fingers nowhere near the end of the probe. Once the probe is placed and we've found the heart beat, the reading is all over the place, ranging from low 60s to high 130s. I know from comparing to a different doppler that lines up with ultrasound readings that our baby's heart rate runs in the high 130s. That being said. The sound is accurate. Given that we can count and do basic math, we are able to ignore the numeric reading and just count beats per minute ourselves. Doing this and comparing to the other doppler I know the sounds is at least reliable.
