USA - Came really fast
I am 9 weeks pregnant and i was able to hear the baby's heartbeat, took about 30 mins to find it but once you know what you’re doing it’s easy. You need to be able to tell your heartbeat from your baby’s. The one thing I liked was that the number on the screen was correct.

USA - Overall amazing
This is awesome I didn't think I would have been able to hear the heart beat at 6 weeks everyone said it was too early but I did in less than five minutes . Definitely worth 50 dollars

USA - Good product
Found the heart beat quickly and clearly but not sure the bpm was correct like a couple other reviews said. Displayed between 120 and 150ish. I am 10 weeks 6 days.

Fantastic product!
Becoming pregnant at 37, I purchased this for added reassurance between doctor appointments. Found the heartbeat at 12 weeks loud and clear. Such a wonderful tool to visit your baby quickly and have peace of mind, knowing that all is well.

Love this! Great peace of mind!
This little device is PRICELESS! I would buy this thing a million times over for the peace of mind it gives. I'm not thrilled about the few and far between ultrasounds that the doctor schedules you for and would like reassurance more often that the baby is fine so I ordered this so I can listen to the baby's heartbeat whenever i want. Baby's heartbeat was very easy to find and this device REALLY gives me peace of mind between doctor visits. I am 14 weeks and can hear the heartbeat very clearly! I love it and use it several times a week if not daily. This is my first pregnancy and having the extra reassurance is priceless. Delivery was a day early (expected to arrive in 3 days but only took 2 days to arrive by priority mail) so I was very satisfied with that. Device also came with a fresh set of batteries which was a nice touch.

Wonderful product
It was a wonderful gift for my daughter, it was so nice to hear my first grandchilds heartbeat in the comfort of our own home. It relieves her anxiety since she had a blighted ovum last year. Thank you

Excellent Purchase!
After having several miscarriages in the past, I wanted the peace of mind between doctors appointments that baby is ok. I was able to find the heartbeat pretty quickly at 14.5 weeks pregnant easing my worries! Definately worth every penny and works great!

Good product
It works perfectly medical grade
Review by Ade / (Posted on 9/4/2018)
The best doppler
After an early miscarriage, this brought us so much relief in between appointments for our following pregnancy! So happy to hear the heartbeat at 10 weeks. Took us almost 10 minutes to find it the first time, but only 30 seconds to find it the next day. Thank you so much for this doppler!! It is really amazing!
Review by Lisa / (Posted on 8/30/2018)
Absolutely amazing!
I saw plenty of reviews that were stunned at the speed of the shipping, but once I ordered I realised that it was shipping from Canada and I thought I would have to wait the full 12 days for it to arrive in Australia... but it arrived in 5! I found my baby's heartbeat within one minute, crystal clear at 175 bpm. I'm 9 weeks along. Such an awesome purchase.
