I loved the custom engravings. I still have two red iPod shuffles with "STEAL THIS" engraved on them, one I occasionally use, one unopened it its box.

Ironically, the reason I have two is because I accidentally ordered two, didn't realize until I received them…and they were non-returnable because of the engravings.

I figured I'd just give one away as a gift, but this was right around the time everyone started getting smartphones so the opportunity to do so never presented itself.
