Great Price! I'm Surprised!

it has been about couple days since i started wearing this device. it checks heart rate every 30 minutes automatically which is pretty cool. for any fitness tracking, i think i have to manually start when i start working out. the cool part is that it actually detects when you fall asleep and record duration by itself. i wanted to find out about that the first night so i didnt touch anything from the device and well it did record my sleep hours including deep and light sleep. Very happy with my purchase.
