I have the bag / the bracelet for a Galaxy Alpha. I am very happy with the bag. The smartphone can even fit it with a thin Spigen into Case and remains completely dry even in heavy sweating. The operation of the display is ok, the side buttons are a bit hard to use - which I think is for the product is hardly relevant anyway. The price / performance ratio is perfect, the delivery was faster than expected and extreme odor I could not identify. A deduction of points there, because a few more cm have done quite well the bracelet.
