It doesn't work It doesn't work.

Works great! I saw done reviews of people having trouble finding the heartbeat and I have noticed that it just takes practice. Also, here's a hint, the baby moves! It's actually really cool to not only hear the heartbeat but you can hear the baby move too. This product has given my wife the peace of mind she has been looking for. Well worth the money.

Happy momma What a relief for a mom to hear the heartbeat any time you want!!!!! I loved the box it came in.( Easy to keep it protected). It was a little hard to find the heartbeat at first and I'm 19 weeks and 4th baby. After finding it, my little family was so excited! I loved the light feature and headphone jack. It is also nice to have a BPM! Thank you!

BPM way off! I ordered and received this doppler rather fast. However, the BPM are extremely off. It fluctuated from 80 to 220, to 120, etc. This is not an accurate machine and cam actually cause more stress than relief. After 2 mmc, and being pregnant with twins, I was hoping for better reassurance.

Love it! After a history of miscarriages, I wanted to be able to listen to my baby's heartbeat whenever I needed reassurance.
