Good dopplers to buy UPDATE

I was considering buying a doppler to use at home. But which ones are good? I don’t want to spend an arm and a leg but I also don’t want to go so cheap that I get one that doesn’t work.

I’m not going to be using a doppler daily, I’m not using it for peace of mind or to make sure my baby is fine. This is going to be used maybe a handful of times to show my two youngest boys the babies heartbeat. If I can’t find it, I know I’m not a medical professional and won’t stress about it. I will always trust my body and my gut instinct to go to the doctor if I feel something is wrong. It’s my third pregnancy so I’m pretty aware of “normal” and “not normal” symptoms. But I appreciate everyone’s concern though. 🥰
