I don't own one, but I was rather intrigued by one and made a point of examining it up close last time I was at MEC (Canadian version of REI). I wasn't impressed.
The lighter portion might be okay, but it's tough to tell since there was no fuel in it. The flashlight portion is a joke. It feels like a shoddily constructed dollar store gizmo that's just waiting for an opportunity to fall apart.
