Defective out of the box - Primus MicronLantern with Piezo Ignition

This lantern arrived today and will be winging its way back tomorrow. The problem? The piezo igniter failed after the first spark. Well, someitmes it does spark but the spark is so tiny it actually won't light the lantern so I'm guessing the piezo doesn't generate enough juice to create a big enough spark. (It lights fine with a match or lighter).

Other than that, the lantern seem to be everything it's advertised to be—as well as a really compact space heater. I've asked to exchange it for a new one so I'm hoping this is a rare problem.
