Now that I have used the Jawbone bracelet for almost two years, which was replaced in the warranty period for free twice for various defects and now is broken again, I switched to this small part. I must confess that I've ordered directly from Apple in the shop, because it was there cheaper than on Amazon. Device immediately works without problems. Steps will be updated immediately after starting the app, which I think is pretty good. In the sleep / wake mode can I go to the app and will have nothing on Tracker push yourself. I am glad that I have to carry no more bracelet because even the Large something was too small for me and the skin at the site was always irritated. The UP Move can beautiful cliffs on the underwear I now, no one does it look and no one is stupid questions. (Except where's your fitness bracelet?) The alarm of the UP band I do not miss, has not really woke me up every time out of my coma-like sleep. The price is unbeatable, and if the battery lasts long enough, I am very satisfied. I will report if there are problems later.
