Is a doppler safe?

Question

I want to buy a doppler but idk if its safe ?? And where do i buy it from any suggestions

Answer

Yes, the issues come from people using them too early and not being able to determine the fetus heartbeat from their own. 
I have a sonline b that I got at baby Doppler.com. I didn’t even try to use it until 12 weeks. At 14 weeks I was able to detect the heartbeat and then I used it once a week until she started moving (she had some pretty strong kicks at 19 weeks).
