Multi-Function Health Monitoring Device

This is a huge lie! This is product is nothing but fake advertising. What I actually received was nothing but a pulse oximeter. No other fubctions. Its took weeks to arrive and it doesnt even turn on. Dont be fooled and order this garabage!

This item only does heart rate & oxygen you all said it also does blood work without pricking my fingers, but it doesn't do bloodwork.

I inserted new batteries n the device keeps saying low n it did not come with batteries
