I just received the Seoul 4xAA lantern from DX. Like the others, it came DOA. However, since I had nothing to lose, I reversed the batteries and bingo, there was light. Apparently, on the inside of the battery case, where there is a "+" on the bottom, I placed the "-" end there, and the same for all four batteries. Replaced the cap and all works. It goes on low first, then high, then strobe, and then off.
On high, it's not as bright as the original Target River Rock lantern, at least that is what I see. However, now I have the option for a low beam.
Overall, same or a bit lower quality than the original Target River Rock lantern. But what did you expect for $16.50 shipped?
