6 in 1 iPod Classic 80GB / 160GB Silicone Case Deluxe Package, Classic Skin + Car + Home / Travel Charger + USB Cable + Armband + Screen Protector + Gift
I use it when I do intense exercise.  I get sweaty.  This armband does nothing to protect my iPod from getting covered in sweat and in turn, getting caked with dried sweat.  This is not good for my iPod in the long term.    I will say though that I've owned it for a few months and it hasn't malfunctioned apart from its design flaw.  But this problem is enough for me to recommend staying away.
