I am very disappointed! 1. the device has massive problems with that view the heartbeat of the unborn child on the phone (max. For 3 sec.), Although a slight palpitations can be heard. 2. I find the sensors are not as good as that of another well-known manufacturer. Had this device (the manufacturer's name I will not mention here, otherwise a wrong evaluation is me od advertising. Accused) in my previous pregnancy and since both the heart sounds, and hiccups were significantly more audible, as here at UnbornHeart. 3. If the sound send via app possible! It has about 10 min. Used to upload a 27 second short recording on SoundCloud to turn only to send the link for it.
Conclusion: Could what it indicates, it would be worth the money. But the not so, but I will revert to the simple Doppler, which although you can only hear, but very good and a lot cheaper ..
