1. The battery is bulky and if you tilt your head up or down too much, the entire lamp will fall off of your head. Tightening the straps does not seem to help. My lamp has fallen off about 10 times in the short time I've had it.2. One of the lights to the side of the big one had a short in it when it arrived and would not always turn on. It was easy to fix but I had to take the entire unit apart to fix it. Turns out the manufacturer had pinched a wire during assembly and that was causing the short. I moved the wire and it has worked fine since then.3. The battery will last about 3 to 4 hours before becoming dim enough to not be usable. You cannot simply put some fresh batteries in but instead have to plug it in and let it charge for hours in order to get a full charge. I have not experimented to find out how long it needs for a full charge yet but have left it charging overnight instead.

Love this headlamp. Suggest getting a different charger - that holds batteries and plugs directly into receptacle and additional batteries. I got plug in charger and 3 pairs of 9900 mAh batteries on amazon for $14, now have nonstop light.

Very bright and decent quality. The battery cover is a bit cheese ball and the batteries tend to pop out just enough to cause the lamp to not work. If your having issues with it, ensure the batteries are fully installed on both ends. The batteries will appear to be in until you press firmly on the battery until you hear them click into place. That has been my only issue with this headlamp. I own 2 of them and gave several as holiday gifts. I recommend this headlamp to all my friends and family. Great price for a very bright and decent quality headlamp that gets used a lot in Alaska’s dark winters.

DIY at home. My vision has worsened and the permits hands free work.2019-03-15, third time I attempted to recharge. AC adapter would no longer plug into the female recharge plug.Examined and there is no way to repair.Extremely disappointed.

Everything was great it's really bright it it really surprised me because the batteries are lasting all day it's been well over a month since I bought they still stay bright most of the night and one thing make sure when you first get your lot and you put it to the charge make sure that light turns green and yes there is a light on there allow for at least 12 to 24 hours to charge before the light turns green but I'm impressed that was a damn good deal enjoy.

Do not throw your money in the trashI bought this flashlight in February 23 2020 only used it maybe three times once the used I put a recharge just one time immediately recharge it not longer take any more charge

The headlamp itself is just ok, the field of view isn't great. I specifically purchased this one because it stated it came with the Samsung batteries and it did not.

The instructions were incomplete and look like they were written by a five-year-old.The light does not resume as advertised.Also it only has a white light, not the two colors.Cheap Chinese crap.
