These were 0.99 on amazon! I bought three because they were so cheap and come with a silicon case AND an arm band. I just used them today during my Nike Training Club workout and it stayed secure and tight while I was doing burpees, presses, jumps, and quick feet! No need to buy the $30 dollar cases, people…They also hold up well while running too (wore them on my 4 mile sub 8:00 min pace run).
