I got one from the same source, same manufacturer, for the same price. Not sure if it's the same model though, the picture is smaller than the one I've got, though it wouldn't be the first time that the pictures aren't what you actually get. But anyway, mine requires two usb ports so requires a powered hub when I use it on the Pandora. You'll be lucky to get a 2.5" one working on the Pandora without external power.
