Terrible guys, don't waste your money like I did on cheap flashlights like this one. It does some tricks, turns off for no reason, and the battery is awful. The brightness is also good for the first 5 minutes, then it decreases because the battery is probably junk. Spend a little more money on a flashlight and find another one.

It is powerful, but the annoying thing for the use I wanted it for at least is that it focuses only with a beam, resulting in illuminating far away but not being convenient for close-up, for example, for doing some work that is mainly for headlamps. Also, it seemed a bit silly to me that it has two lenses, but instead of one being for close-up and the other for far away or simply being able to turn them both on for better performance, in the end, one is just warm white and the other is cool.

The battery that comes with it is unacceptable. It discharges before 15 minutes have even passed. I have ordered a new branded battery, and that's when I will judge the camera better. Although I haven't tested it in rain or water in general, I don't think you can call it waterproof, especially in the battery compartment and charging port. It includes a head strap as shown in the photo and a USB charging cable (without a charger).

As soon as I received it, I held the battery in my hands and it felt like a feather, which made me suspicious. I completely discharged it and measured it with an XTAR charger, which showed that it was only 4800mAh, which it is not! I measured 240mAh, not even 1000! So the battery is useless from the beginning and you will need to get another one if you want to use it. Additionally, the cover of the USB port was already cut and the rubber, with minimal force, tore when I tried to attach it to the clip.
EDIT: After exactly 2 weeks, it stopped working without being wet, dropped, or used excessively

I have had it for a short time but I am completely satisfied.
Very powerful light on both lamps. You adjust the intensity by holding down the button.
Very good battery life and a strong head strap without pressure.
I mainly use it for hiking and photography.
5/5

Very powerful lighting but the problem for me is that the opening button doesn't focus, it makes it difficult for me to open and close because I have to keep opening and closing it. It's not so user-friendly. I believe that if you want it for a repair job, it's good and considering its price, it's worth it for the reason I mentioned.

The main problem is the battery, it is definitely not 3400 mah (and it doesn't change).
The build quality is very mediocre.
The brightness cannot be adjusted.

It has a spotlight in the middle and a second brighter circle further out in one option. I would prefer the spotlight to be less focused and more open in radius. Besides, the second option has wider coverage with a smaller radius of action

+ Strong
- Small strap
- Poor battery (the battery weighs 20g less than a branded one and lasts a little)
If you can change the battery with a better one (easy job), it is excellent for the price.

Very good for its price. It does its job. The downside is that you can't combine the two LEDs it has simultaneously. It was tested in night fishing and it was very good.

It has only two functions, one LED lights up white and then the other LED lights up warm. Nothing else. Just a flashlight. Rechargeable. For its price, it's fine

Terrible... the lens broke in less than a month.
We bought 2 pairs, one for me and one for my friend. And both broke almost on the same day.
