Fetal Doppler Heartbeat Detector
Got Doppler, everything works. With gel, the heart is audible normally, the heart determines. The seller is sociable, sent immediately as appeared in stock, as a gift put an electronic thermometer.
Everything is fine, everyone is happy. Everything works. High-precision this device is not called, but how some landmark can be used! The seller sent a couple of days after payment, it came quickly.
I ordered from Russia to Mo. Delivery took 9 days. Brought the courier personally in hand, packed well-the box was not wrinkled, Doppler whole. Inside everything is laid with foam rubber. Batteries were not included, gifts too. At the request, the seller sent an email to the instruction on the Russian. Doppler himself works well, heartbeat at 18 weeks was found quickly, but only with gel-without gel very vague sounds. Through the headphones, too, everything is well audible. I'm happy!
