Teamyo Smart Heart Rate Bracelet

This Teamyo Smart Heart Rate Bracelet works well. I used it off and on for around 5 years. Never had a problem with it. I worked in manufacturing so there are some scratches on the face but not enough to hinder reading it. The app is easy to use as well. The original box, instructions and charging cord is included. See the picture of the box for product functions. It says it is waterproof but I never got it wet. I took it off if I was going to be in water. It will need to be charged before using.
