Nevermind the vendor evaluation phase where there is nothing wrong, fast delivery and product conformity. The product itself: As I said just before, this armband is consistent with the description by the seller. The quality is very satisfactory and the cuff with maintaining large enough scratch to fit all. The pocket is big enough to slide his Samsung Galaxy S2. The clear plastic front panel does not interfere with the touch phone use.
The small downside: Its size very precisely adjusted to the phone, it is very difficult to extract the phone from its support especially as the screen literally adheres to the clear plastic front panel. It takes me several long minutes to take the phone out of the holder.
Finally, despite this drawback that is not a defect, it is a great product that perfectly fulfilled its role.
