I bought this when I was 14 weeks and I found the heartbeat straight away! I would definately recommend this to other mums-to-be. As I am a first time mum, it puts my mind at rest as I can hear the babies movements, heartbeat and kicks. I am now 17 weeks and 6 days and I still find that my baby is low down and can only feel little flutters.
The only problems I found about this product is that they don't supply you with enough gel so you I ended up buying another 3 bottles. Also, I still haven't worked out how to record my babies heartbeat on my laptop so I still can't send my mum or sisters the babies heartbeat. This is a problem to me as I live in Essex and all of my family live in Manchester.
However, This is the best item I have bought from Amazon.
