High quality, with detailed instructions in English, really good product, works very well, i can clearly listen to the sounds of my baby and very fast delivery! No battery inside, but i'm happy with buying it anyway!

Battery is included just put it in and the machine is ready to go. It worked right with the first try clear heartbeat sounds to hear. Love this machine and will use it often
