Bone Collection Sports Armband for Phone

I have had this about 3 months now--during which time I have averaged about 10-15 miles a week running. The softness of the plastic agains the skin is a plus. Compared to my old arm band with a plastic sheath, the four-corner grip and open design has made the screen more easily accessible and the runs more fun, as I can mess with the music more feely. The only downside is that it is a big jiggly and would perhaps benefit from a wider band. The jiggling puts stress on the velcro, which seems to be aging quickly. The velcro has never released while running, but a couple of times, when standing still and switching play lists, I twisted the phone slightly to see it better and the the velcro popped loose--causing the phone to sort of spring off my arm (luckily, straight into my hand). Based on this, I estimate this arm band has a life span of about 500 miles. A huge improvement from the sheath design (or pockets), but wish the arm band was wider and/or the velcro stronger.
