text: Seems to be good quality. Had this for a few months now and use it every day. I think I miss read this and believe its for use on a hard hat. I use it on my head directly and the battery pack is a little heavy without the supporting ring of the hard hat holding it up. Once i adjusted the head strap a little it made a better fit, and also learned the best place to seat it on my head. I like the adjustable brightness and beam focus as well.
