It is incredible for its price and very powerful! It comes with a built-in 18650 battery, but one can also add a second extra battery when it runs out. It charges with a very practical USB. It has many beam and intensity options. One can make multiple combinations. Also, if you press the button continuously, the intensity adjusts from very low to high, and you can leave it where you want. Additionally, it has a photocell (motion sensor), and you can activate it by simply waving your hand in front of it (if you have dirty hands, for example, when fishing or with animals). Finally, the lens is detachable from the headband and has a magnetic base with a very strong magnet, so you can place it on any metallic surface. It really does everything. As a negative, I only mention the size and weight, which I consider reasonable!

Very good but..... it needed replacement twice... the first time the buttons didn't work properly... the second time it didn't charge well and I asked for a refund because I believe I would have the same issue with the third one...... unfortunately.....
