Is buying a Fetal Doppler worth it?

Im 15 weeks and I’m thinking of buying one. I have enough common sense to know that I’m not medically trained and would never use it to “ease my mind” if I had a feeling something was wrong because a beating heart doesn’t mean a healthy heart. I would buy it purely for a bonding experience,m and the excitement of hearing your baby.

But I know that if I ever struggled to find the heartbeat it would worry me a little. It’s definitely got pros and cons. I’m interested in your experience/thoughts?
