Don't waist your money!
Heart rate is extremely inaccurate. It has recorded a heart rate of 46 (not possible, my pacemaker will keep my pulse at or above 60) and 196. At 196 BPM I would have had extreme chest pain - I felt none. The auto screen on function is difficult to get on when I want it to, but driving or riding in a car it is on far more than it is off. Very annoying when driving at night! The Android app is very user unfriendly. Information that is displayed in an easy to read format on other fitness watches is difficult to find or not even available! Of the 4 fitness watches that I have used or tried this is by far the worst. I had a non-waterproof one with the same type of Heart Rate Monitor that was very accurate, so it is the way that this one was designed.<br />Best features: waterproof to 1 meter and the band.<br />Worst features: everything else!
