Query: Poor Quality Hardware

What a nice idea -- and I *do* like my JumpDrive USB memory. But the JumpDrive Sport I ordered had problems right out of the box. The volume/navigation toggle switch didn't work well (couldn't consistently adjust the volume) and within a couple minutes failed entirely. Back it goes for a refund... Darn. For the few minutes that it worked the music sounded pretty good.
