Dear Customer Our product made in Qinhuangdao, Hebei Province, PEOPLES REPUBLIC OF CHINA,but our warehouse in IL,US.Our warehouse has product in stock,and we all of goods from our warehouse to your adress.

Does it come with the batteries?

No, it did not come with batteries. It takes two AAA batteries not included. It does come with a little carrying case.

What is the difference between cms50 dl and the cms50 na ?

The cms50dl is an led readout and the cms50na is an OLED readout. The OLED is a much higher contrast and brighter display, higher pixel, better quality readout. Also the cms50na has rotatable display where the dl does not, i believe. For the money I really like our cms50na! Its lightweight but works well. Seems fairly simple and accurate.

Does this device have acoustic pulse monitoring as well? Is it beeping with the heart rate?

Sorry dear,our 50NA could pulse monitoring，but no have acoustic,it trait is monitor accurate and have OLED display.
