quality problem over time

As against this, not often found test after several months. I have my own wrist since early November 2013. After 8 months:
- I had to buy several times tip because they do not hold well. Basically avoid playing sports with ... It's a shame
- The single button showed signs of weakness in recent weeks and now: he definitely dropped last week. More possible to switch to night mode or nap timer or short, unusable Bracelet

The service was quite responsive and sent me a new bracelet after weeks of waiting.

New bracelet who also passed away after 6 months of normal use (same problem: button and LED HS, something has to break inside).

By cons for me: no battery problem, load, or with the android app. Everything rolls
