Actually, this bracelet is not so bad: the I-Phone past good use exactly in the pocket, the touch display can be explained by the plastic film, the processing of the bracelet appears solid and the price is cheap. But what good is a, if the manufacturer donated just 37 cm band that will fit around "every normal arm"? I am by no means a muscleman, but at length I get the tape just wrapped around my upper arm times, let alone that I can then tighten the loop and there. With jacket, it is not possible to close the bracelet .. In order to arm it's just so, but in this position bothers me the tape during sports.
Potential buyers should therefore measure the arm circumference before ordering. In an upper arm circumference over 30 cm I do not recommend the purchase. I then left the bracelet my daughter that fits it. With track jacket but it is already nearly even with their upper arms when the arm does not want to be cut off.
Conclusion: For the good functionality, there are 3 stars. But if the manufacturer obviously at the wrong end, come to the tape length, saves, then the functionality is useful to me unfortunately nothing and the Sport Armband for me useless. If I bought it, it would have declined.
