Good product but points to review.

The concept is good, I bought and never having to leave my smartphone on the subway or in risky places
but also to save some battery and not be bothered by cables fragile headphones.
At least there, everything goes in the hole and remains free to make sudden movements and no longer seeks the headphones !!!

- Good otherwise passable sound quality but good is so cheap as it is assumed product.
- Additional features are useless, except maybe an hour.
- The touch not respond very well because it is not coming from the LCD but actually decaf buttons at the screen,
at the same time with the software calibrator, always support well above the menu to access it.
- THE FLAT BIG !!!!!

I lost the watch at a brisk walk, because it is detachable bracelet !!!
A beautiful Annerie enable it when you see that fixing is very summary.
IT simply does not take much to see her off in a sudden movement.

So I end up with a plastic strap and all my flights music ...
I do not regret buying, but I am disappointed by this point in the design.

The only possible security to prevent this, is to make sure that the headphones jack and always connected,
to hold the watch in his fall.

I'll buy one if it NEGATIVE POINT is corrected in another version
(I have no desire to put the cyanolite on plastic)
