content: I suppose in some literal sense this thing does its job: it keeps your ipod attached to your arm. But once it's there your ipod just flops all over the place. Don't try moving too much--in other words, don't try too much "sport" with this thing on. The product would be effective for things like sitting around, maybe going for nice easy strolls. But then I would think just sticking the ipod in a pocket might work out just fine. Maybe there are better 30GB ipod sleeves out there if you want to run around, or maybe you need a nano or a shuffle. You certainly don't need this.
