## Description

Product Description

Review: Good product - Like product, value for money ,ease of use good quality
Review: Good product - To be honest… i was a bit suspicious of this product if it would work or not. At first I struggled to find a heart beat but i got a hang of it finally and it is SO SO CLEAR. You can hear the heartbeat clearly if you know what a fetal heart beat sounds like ( Refer Youtube ). I’m so happy with this. Lets see for how long this would work. Box says 6 months warranty. One more thing, it says no gel required but i did use alovera gel as coupling agent. If you read the manual given with it, it says to use a appropriate coupling agent.
