Well got the flashlight and looked it over, mostly gold plated contacts, the focus part works good. I brought it in to work to compare to some coworkers 100 dollar led flashlights. It appears both use the same smd led array and similar focus lens. Only real difference was mine has 3 aaa batteries and theirs use 4 aaa. And mine will strobe flash and is a lil smaller. It does suck the battery juice down fairly quick. It feels fairly rugged, made out of alum and has o rings.
