Easy to use.
I ordered Baby Doppler to check a hearbeat of my baby between appointments. The device is pretty compact. The holder for probe is too tight and it's not easy to remove the probe back. It doesn't take too much time to find a heartbeat (I'm on 23d week). I'm not sure if the displayed rate is 100% correct, because it changes quickly if to move the probe slightly, but the sound is clear and laud. There is a small tube of gel, but you need just a tiny amount.
