Bests & Worsts Reviews from Amazon

Got this based on a lot of good reviews. I am currently working on a remodel in the basement and use a headlight constantly for all sorts of things. The other one I have is a larger rechargable (with the battery pack at the back of the head) and I wanted something lighter. First couple of charge go-rounds were great. I got a good solid 6-8 hrs on low beam (all I really need to help see things) but now, going on its 4th charge, it seems to only last about 3 1/2 hours or so... Too bad I let it sit unused for a couple of weeks and now it is past the return date, so I guess I have a light that needs frequent charging. Fortunately it has a usb cord so I do have charging options, but I wish I didn't need that option. So it goes... Now a week later, I'm finding that the thing won't even stay on for an hour. It will go off and I can turn it back on again but it will only stay on for about another 10 minutes. Charge it overnight and get another hour of use out of it, repeat.... I thought that maybe the batteries might have been substandard (read: junk) and figured I'd change them for some AAA I have but, despite there being a locking clip (which promptly broke off) and divots on the (2) sides and obvious hinges at the bottom, the thing is glued shut....!!!??? I guess "No user serviceable parts inside". I guess the moral of the story could be that you get what you pay for, but I don't believe that this was worth the cost.
