I hate this product, it doesn't work.

not user friendly. Read manual.

Not a fan of how long it took me and my wife to figure out how to use it. It definitely has a learning curve.

This doppler does not provide the correct reading. I guess the heart beat I was hearing with it was my own (rate always between 80-90) & it could never actually catch the baby's heart beat. Checked with my doctor and was informed that the accurate ones usually cost around $500 and I'm wasting my money on this doppler. So I returned it.

Product works for a piece of mind, but heart rate slightly off compared to today apt at obgyn 130vs150. The app does NOT work!! Crashes every time we try to record his heart beat!!! I think I’ll keep the product because I really loved hearing him! Terrible app though

Sound quality is not great at all, very underwhelming, doesn’t work well with aloe vera or other gels other than the “sound enhancing gel” that comes with the product, that gel being very small. (Product tried at 22 weeks pregnant)
