Excellent. Small in size, ideal for indoor use. Very good solution for security. I use it in an open space and it is quite good. It is not mentioned anywhere in the descriptions, but it has a strobe function! By pressing the switch 3-4 times quickly, the strobe is activated!

First of all, it doesn't zoom!
After a month of use without dropping or getting wet, it started to have interruptions and never turned on again.
It has a very poor switch.
I think anyone who buys it will waste their money.

You need to buy an adapter to charge the flashlight or use another device with a USB port to charge it. It has a bright indicator on the button, green or red, which is supposed to show if it is charging, but it doesn't do that. Also, when you're not using the flashlight, the indicator light turns on whenever it wants and it loses power and discharges for no reason. It lights up well up to 60 meters on the strong setting. It is heavy, durable, and has a good magnet.

It is good!
I have stronger lenses, but I find this one very convenient due to its size and the fact that it doesn't have many scales

I will start with the negatives, you have to be careful where you place the button, it is relatively sensitive. Although it is powerful at a short distance, you cannot focus it a bit further away and it lacks zoom compared to the nitecore 1000lm, it is weaker. Its performance decreases relatively quickly due to heat, but it returns to its initial performance when it cools down. On the positive side, it is practical in size, fitting everywhere at 12 centimeters. Tested in continuous operation for 5+ hours, it still worked even though it had heated up to the point where holding it in hand was impossible. It has a sturdy construction and is relatively waterproof, but not suitable for diving. It has a low brightness mode and a fast flashing mode. In my opinion, it is practical but not ideal for security personnel. I would recommend it to cyclists as long as they don't use the fast flashing mode, and for general work outside the house.
