By the time I get it - I will be in my 9th week. My friend said with the exact same one I got that she was able to hear her daughter as early as 7.5 weeks ish - she said it was great and was actually hospitalized due to water breaking in 5th month and the hosp used her doppler too. Here is hoping my little bambino has a strong one that I will be able to listen to. If so -- I will be able ot charge ppl to come and try it out LOL JK!
I've heard of 'em but I don't own one although it would be nice to have. But i also heard that it's not as powerful as one's in doctor's office so you can't really hear anything until 10+ weeks. But i don't know if it's true or not, just things i've heard. Let me know if you like yours maybe i'll get one too***
