It is the third flashlight from Nitecore that I have purchased because I liked the tilt that the head can take and because it has an independent red light. Its size is good, it is big enough to fit in keys, for example, but it is small and practical to take with you. It charges via USB and has a charging indicator light, red light while charging which turns green once it is fully charged. The major downside is that after a few months of use, the light started flickering on the high setting, while it works fine on the low setting. I have encountered this flaw before in similar Nitecore flashlights, and I have also read about it on international forums on the internet. Of course, all of this without heavy use, as I keep this particular flashlight on my nightstand and it has not been dropped or anything, it just suddenly started flickering on the high setting. It doesn't cost much money, at least I bought it for 15 euros, but now it is being sold for much higher prices, and for that amount of money, unfortunately, it is not worth the risk. The same problem occurred with a flashlight of the same model, so it is a flaw of this model. Forget about the warranty, it says it has one, but if you go to the store for a replacement, you won't get anywhere because, from what I understand, there is neither a dealership nor a service center.
