The many reviews spoke for sch, but we wanted to convince ourselves.
Two days later the package arrived with us, was also included, the gel for sonication.
Of course, immediately unpacked and tried.
I must say that I am in the 10th week of pregnancy. Inserted batteries and off we went, about 3 minutes later, I could easily hear the little heartbeat and see on the display.
We are absolutely thrilled and really can recommend to anyone who is possibly a little anxious this investment.
Earned 5 stars! :)
