Home fetal Doppler!

WAAAAAAAA my friend has given me her home fetal Doppler and I found baby's heartbeat in literally a second!!!!!! This is the best thing ever existed !!!!!!! I definitely recommend !!! Heartbeat was at 175. Was so loud and clear! Hubby was so happy with it too!!! I'm 10 weeks 4 days but I know people can find it from 9! 
Anyone else tried ?
