Hey. I try to carefully monitor my health, as very often I put my body under quite a lot of stress. For this, on the advice of friends, I purchased a fitness tracker, which helps me very well. I ordered this device on the Fitbit website, as I read that they are one of the most reliable. But when I got this device, I couldn’t figure out how to use it properly, so I contact fitbit and they gave me great advice, which I was happy with.
