Look they have horrible translations in instructions and ads on Amazon but let me tell you the watch is great A++ I got 3 compliments on this watch this week while I I had a watch (plural) and tried Samsung and others. I have to say I really enjoy having a very accurate sleep/heart/fitness/weather/watch on my wrist that I'm not worried about breaking or damaging. If I crack it, I just grab another one from the bin. These watches are actually very good, maybe even great, no matter the price. I have a $10,000 Rolex watch and I go to the ocean of planet Omega, but I had a boardroom meeting today and then I changed the oil on my GTI son. He never took off the watch and never thought about it. then i noticed you said you had a great heart rate and you followed your steps etc etc etc trust me its a good watch and a fantastic price. Just remember the instructions aren't great but the product is there. Oh and the battery life just wait you'll see I ran 72 hours and it still worked fine TInwoo you have a great product. Kind regards.
