Baby Sound B Baby Heartbeat Monitor with Built-in Probe & LCD
- Product Review (submitted on December 20, 2015):
- I am chubby with a big belly ,but we found heartbeat at 9 weeks 4 days. We first thought it would be better if the probe is separate from the unit itself, but it works just as well (found heartbeat at 9.5 weeks!). Only complain is that the speaker is not built-in and using the earphone could potentially damage your hearing if you're not careful. We use an external speaker and problem solved.
