I have been seeing beamshots of the Ultrafire WF-1300L and must say it is an impressive light. And yet I also hear that the build quality of the light can be pretty awful. So what's the verdict on this light? Is there a place to buy one of these lights that can assure that what I buy is one of the good ones of the batch, or are they pretty much all shoddy? In other words, would you recommend that I pass on buying it, and look at another light of better build quality? If so, what is comparable in terms of light output and size? Many thanks.
