The lens is great!! Powerful light, comfortable on the head, high-quality construction!! It lasts me about 2-3 days on the second setting, of course, I turn it off when it's not necessary. Charging time is a whole night, and when you wake up, it's ready! I got it for 62€ (with a price notification, as it was originally 85)

For now, I have no complaint.
I haven't bothered to calculate how long the flashlight battery lasts in practice, but my general feeling is that it lasts quite a while (usually I use it on the second setting for about 70% of its operating time).
Charging it with a cable connection on the flashlight is very convenient, but not particularly fast. However, I haven't gone through the process of looking for a separate charger since I almost always charge it when I go to sleep.
I have run out of battery twice during the time I use it, once because I neglected to charge it in time, and the other time because I had it on for several hours (my forehead had gotten quite warm anyway, so I had to stop working).

Very good! It's worth its money, which is not little! Note that it has a warranty and can be repaired! Very, very essential and important!!!! You don't throw it away if it breaks! If something happens within the warranty, they repair or replace it!

Excellent flashlight. Amazing build quality. It's not meant to be submerged in water, but it works comfortably in rain. It has 5 levels to adjust the brightness you need. The first level is like a candle. The fifth level turns night into day. Obviously, the higher the level, the faster the battery drains. It has a strobe function to blind the "unwanted" and finally, it has adjustable straps that fit on your head to keep it stable. Completely satisfied with my purchase. I couldn't ask for more for the money.

It is a tool that really solves your hands, very good brightness. I work with it for electrical use, the third brightness level is more than enough for me and it lasts for many hours.

Very good. It's worth its money. I've been using it for 2 years and it hasn't had any issues. Only the battery needs charging after continuous use in very intense light (high brightness level). Personally, I wouldn't change it for anything

Amazing weight very bright but not worth the money. The battery lasts at most 2 hours for professional use. In case someone needs light for many hours, they should not buy it unless they also buy 10 batteries. I regret my purchase and now I am looking for a better one
