Review on KCY Bluetooth Percentage Composition Smartphone by Jill Brenneis

According to my experience, this activity monitor did not live up to expectations. The pros were that it had Bluetooth connectivity and could track STEPS. However the cons far outweighed the pros as it couldn't accurately record heart rate or monitor sleep .The design was also clunky and uncomfortable to wear during exercise. Overall, I wouldn't recommend this product to anyone serious about their fitness goals..
