The iPhone 4 model (see above) is a little more robust by the processing. Exactly the point on the bracelet, which is broken with its predecessor, was once more extra reinforced (there is now nothing more can happen).
In summary in keywords (run 3-4 times a week, each 10 - 20km):
- Bracelet fits perfectly / have never slips
- Continuously variable size adjustment possible
- Running in the rain is no problem, because the bracelet surrounds the iPhone 4 (even my little Extra flap above)
- IPhone 4 fits perfectly into the shell
- Outputs for headset available
- Operation possible without any problems through the transparent protection
- Noble, clean processing
Dignity and even the full number of stars awarded, however, have so far not tested comparative products. And in this case you should still leave room for improvement openly.
If any further questions - just here to set a comment for review.
