So far the Jawbone Up is meeting my expectations. The large is a bit small for my wrist but I make it work out.
I had to install, delete then re-install the app on my iPhone in order to get it to recognize the Jawbone Up was plugged in and to get it to sync . Navigation through the app is intuitive.
I had one of these and upgraded after it stopped working only 4 months after purchase. I still have the upgraded model, but wanted a backup so that charging would be easier. I usually charge it in the am when I get up every 7-10 days then forget to put it on when I go out to exercise. I wanted to keep accurate so I can wear both. Plus this one is easier to put on I almost Lost my UP 2 because it easily becomes un attached.
