I actually really like this headlamp. I was initially annoyed that the 18650 battery was not replaceable, but the functionality and size make me kinda meh about it.
This headlamp is small, very bright, rechargable and easily removable from the strap to use the strong magnet end to stick it to steel objects.
The spotlight is really intense and the bright, even light of the COB floodlight are both great feature in a headlamp so small and light. It has a soft silicone plug/ cover for the micro USB charger port and switch that does a great job of keeping dust and moisture out.
Hopefully the manufacturer decides to make the magnetic end cap removable so batteries can be swapped instead of only recharged. It sucks knowing I have to throw the whole light away when the battery dies. That's a big downside to me and one that makes me rethink my purchase. Other than that, I like it!

I purchased this on Amazon, I tested it out and found that the top LED spot, overheats within a minute, after 2 minutes of constant on, I had to remove it from my forehead. there might be a risk of fire, if it were left unattended. I have a collection of over 300 LED flashlights & headlights, I know the cabbage in my own garden. On the other hand, the bottom COB LED is fantastic, a very bright flood light, which can double as a work light/ walking dogs at night, I use the COB everyday and have yet to recharge it. Please don't get me wrong, I don't mean to degrade the seller in anyway but, the housing of the headlight, has no means of air ventilation, ie: can't be cooled down. Also good to note, if you turn on either light, & keep pressing the power button, you can lower/raise the brightness level, starts off on high. the seller also includes a small 3-AAA battery mini COB light, (hi/low/flash, which for me, is very useful, handy magnet, for the price, can't beat it. To be honest, it's better suited for adults.

I was looking for 3 qualities in a headlamp: USB rechargeable, highly adjustable (especially the ability to point downwards, to use as a work light) and a soft diffuse light (not a small spot). This does all 3, *and* has very good battery life. There are lighter weight headlamps than this, but I think it's a good compromise between lightweight, battery life and adjustability. Also, this lamp has a spot light in addition to the diffuse COB light, which should make it useful for outdoor use as well.

I wish it had different brightnesses for main light as well as a red light. Very bright and really good at attracting bugs to your face. Nice that it is rechargeable. Not very comfortable to wear long term with plastic right on forehead. Does what it's meant to tho and able to see in the dark with it.

Love this thing. The COB is great for bench work with poor lighting. Use it all the time. Can't speak to the durability but so far so good.

Good product very satisfied. Great seller.

Light weight, good head strap, very bright. The tilt flunction is quite handy.
So far so good!

I really like it it is accountable headlight I liked for work
