Looks like the same as the ones I picked up from Deal Extreme this winter:

So far, I've been very pleased (major upgrade from the PB Blaze 2W I was running). Only down side (at least for the DE ones I got) is the status light on the switch is always lit and draining the battery so I need to unplug the packs when not in use.
