Sonoline B Baby Activity & Heartbeat Monitor
- Product Review (submitted on December 24, 2018):
- I've never used any other doppler before, so I dont really have anything to compare it to, but it seems to work great. I found fetal heart tones at 9 weeks in about 10 minutes. Super excited about it! Although I feel paranoid for even owning this, it does put my mind at ease. It did take about 7 or 8 days to arrive.
