This is a very good product and was shipped as quickly as I selected. Initially, at 12 weeks pregnant, it was hard to detect the heartbeat, but after a few attempts, I was successful. Now, at 14 weeks pregnant, I can find the baby's heartbeat almost instantly. Importantly, the included manual was in Chinese. I contacted the seller for an English manual, and received it the same day.

This is a great product. I'm still only 9 weeks along, and it's a little hard to hear the baby's heartbeat.

The request was made on August 31st and arrived at my home on September 30th. It arrived in Brazil very quickly; the delay was due to the office being on strike. Highly approved, and the response was prompt.

The product functions, however, the packaging arrived in a disorganized state.
