Affordable and works great!
Ordered 2 day shipping and the item arrived on the date originally stated. Very easy to use, found my baby girls heart beat right away (currently 16w). The item is a good size and able to fit in my purse if I need to take it with me. Also includes batteries and gel which is a plus.

Best doppler yet
I've had other dopplers that were just mostly static. Took me a while to find the heartbeat but once I did it was steady and clear.

Pretty good just took long to find my sons heart beat @ 15w 6days

Fine for hearing heart beat- not reliable for medical use
I dropped a star because the numeric reading is nowhere close to accurate. The numbers read 109+ before the probe has ever been placed- and fingers nowhere near the end of the probe. Once the probe is placed and we've found the heart beat, the reading is all over the place, ranging from low 60s to high 130s. I know from comparing to a different doppler that lines up with ultrasound readings that our baby's heart rate runs in the high 130s. That being said. The sound is accurate. Given that we can count and do basic math, we are able to ignore the numeric reading and just count beats per minute ourselves. Doing this and comparing to the other doppler I know the sounds is at least reliable.

Huge Peace of Mind!
Just got it and was able to find the heartbeat pretty quickly. It's not entirely accurate on the FHR, but just hearing the heartbeat is really all I needed. Totally worth the money and peace of mind.

Highly Recommend this!
I absolutely love this Doppler! I was able to find the heartbeat right away and it sounds clearly which is great because other Doppler’s I had tried sounded like a lot of static. I highly recommend it! The only downside is the reading of the heartbeat is a bit confusing not too accurate.

Love it!!! ????
Pealed the label off the screen and there were lines there for about a minute. I thought it may have been damaged but all is okay with it now! Since I live in a rural area it took longer than expected to get to me but it was definitely worth the wait!
