This is the second cuff that I buy (the first was a Decatlon iPhone). It is really very comfortable. It fits perfectly on the arm, the material is nice, it does not move. In short, it is completely forgotten. But by design, I'm afraid to run with wet temp. Indeed, the top of the phone is just covered by a flap that inspires me a lot of confidence ... One last thing, the Galaxy S2 holds everything just inside. It should even force a little because the phone screen hangs a bit against the protective plastic film from the cuff. If your phone is in a shell, you will need to remove the armband.
