I use one I borrowed from a friend and love it! There has been times I don’t feel twin B so it’s made me feel better and there are times I just want to hear them. 😃
I thought it worked ok! I bought this Doppler like 5 years ago when I was pregnant with my son and had a scare during my pregnancy. I couldnt really hear him until I was like 16 weeks but idk if it has to do with me being on the chubby side. Lol remember to always have lube for the Doppler so it glides easily on your belly and so that you can hear the baby easily too ☺️
