Build quality looks good but that's the only nice thing I can say about this light. Measured light output degrades very rapidly (down to 1000 lumens @ 5min., 500 lumens @ 60min.) in the blitz mode so realistically "FAR LESS POWERFUL THAN CLAIMED". Single program user interface requires clicking through 4 steady and 2 flash modes to toggle between different preset levels + the mode button feel is pretty stiff. The strap mount doesn't hold the light tight enough to keep the beam from bouncing on rough ground + may be unreliable since I've seen a tear failure on one of the Dayblazer 1500 online reviews and I've experienced the same thing with one of my old 1100's.
Liked the product. the only problem is the rubber turn on button broke and I have had to put a plastic part under it to make it work.
