Review: Runs big - Good quality! Definitely a great knock off of the orginal arm band.. however, size DOWN
Review: Garbage - The reviews that this thing fit OK at the start, but after only wear on it four times, it already slips off my arm. Not sure if the solution is to buy a size smaller than you’re supposed to, but it’s not worth the money at all.
