It probably took a good 21 days to arrive, because I also ordered 2 26650 Li batteries with it, which slows down the shipping. However, when it finally did arrive, Wow! This thing is brighter than my Sky Ray Kung, which has 4 Cree XML-U6 LEDs, and it even seems as bright or brighter than my huge Ryobi 18 v HID spotlight! The beam is not adjustable, but it's a very nice combination of throw and flood & seems to reach out as far as the Ryobi. I don't know how long the run time is going to be yet, but so far, I'm ultra satisfied with this fashlight. My only complaint was that when received, it was in strobe or SOS mode, and there was no kind of manual to tell me how to get it changed back to regular mode. Even with my moderate experience level, it took me a while to finally figure out how to change that mode. They need to provide some instructions with this otherwise fine light!
