I literally JUST ordered one an hour ago on Groupon for 19.99… same one on Amazon for 80
I have the Sonoline B Doppler. We usually find her in about 10 seconds! Such a great feeling and bonding experience.
I did buy it online tho..BabyDoppler.com
i have the Sonoline B doppler as well! i’m still only 13 weeks so it usually takes me a few minutes to find the heartbeat but it does work!
Occasionally I’ll see them on Facebook marketplace. They are super cool to continue to hear baby when you want, but I will say it caused me more anxiety when I couldn’t immediately find baby. I ended up giving mine away to a friend.
