Query: I cant Believe so many bad reiviews

I bought this product when I was PG with my first child 2 years ago and loved it. It did take a few times to hear the heartbeat, but once I figured out how it worked, it was more easy to find in future uses. I found that I was turning the valume to high and once I fixed that mistake all the background noise went doun. I recomend u put in on the middle valume setting. I loned it to a friend and she says she cant here the heartbeat, so I dont understand why some can and some cant. I am PG again and will be bying another since my friend boke my old one. I would recomend this product, but dont waste youre money on the deluxe model, just for incase u are one of thouse who cant figure it out.
