I have had the flashlight for almost 4 years and I have not changed the battery... it is used in difficult conditions (very hot, very cold, in oils, petroleum, etc.) and apart from some glitches sometimes in selecting the mode, it has not presented any issues... it has fallen countless times to the point where it is crooked in the front and it works flawlessly.. I would easily buy it again if I were to buy a flashlight tomorrow... the magnetic charging is also very good!

I have been the owner of this specific lens for 4 years now (October 2018) with almost daily use due to work on the low scale (100 lumens) and occasional turbo use. In terms of its size, beam distance of 600 meters, and 90,000 candela, I have not been able to find anything comparable in terms of power until today. As for the issue with the stairs, it also appeared for me, I used compressed air on the switch in case dust had accumulated and the problem was fixed.

The lens is very good. Excellent, however, for a few months. The problems mentioned in the other reviews are true. After some time, the lighting scales may start to stick and eventually stop working completely. I have tried almost all models of klarus flashlights, but they all have this issue. They are all great flashlights, but after some time, they will break for various reasons. One may burn the circuit board, another may detach the LED from the front. Those who have the turbo version (which is great in turbo mode, but the flashlight cannot handle it for more than a few seconds, as the manufacturer states) face problems when someone holds it for 5 seconds, resulting in issues. It would be better if the turbo mode didn't exist. Non-existent service, they fix all the damages outside of warranty. It's not worth the money for professional use, and I don't think it's worth it for personal use either, unless you only use it three times a year.

Very good lens so far... I have had it for a year and it is powerful... What is happening to me now is that it gets stuck on the stairs and doesn't change them, and I have to completely close it in order for it to move forward and adjust the stairs. If it didn't have this issue, it would be perfect... Maybe it only happens in mine...

After 2 years of use, it stopped working. I changed 2 batteries but the problem remains. I will check the charging cable and upload a new one.

Sturdy construction, easy and relatively fast charging, powerful light, it has three lighting modes that make it even more practical, especially in small spaces. The Hunting Kit includes user-friendly accessories.

The lens is very good and worth its money!!!! It reaches the advertised 600 meters comfortably, but don't expect to see much with the naked eye at such a distance!!!! It is very good and comfortable even if you have it on you!!!! It illuminates quite well and has a brighter spot in the center. The mode it has to blind at night where the lens flashes is very nice too!!!!

I have had it for at least 2 years. It has never betrayed me. It warns when the battery is running out. Its battery lasts very long and even after 2-3 months without charging, it does not lose power. It has 3 levels of brightness. On the downside: I would like it to have a tougher casing as it slipped on the asphalt and got scratched, and when it stays on for about 5 minutes, it gets warm in front of the lamp, but without any issues. Very good operationally, worth its money.
