2 of 5 Please issue a return product label April 23, 2022
Reviewer: Mark Williams from MountainHome, AR United States  
I am not satisfied from day one of using this product. Poor ergonomics, button positions not practical, and I am a Nitecore fanatic.

Reviewer: Will WillybkKoenig from Winfield, IL Winfiel, ILUnited States  
One of the best tactical lights that I have ever seen.  Good features, USB C charging, fast tactical (20K output) switch in a small, compact package.  Nitecore has really delivered on this one!  Also great / quick shipping.

5 of 5 Did it's job too well April 18, 2022
Reviewer: Doza from Japan  
Upon receipt of this "Tiny Monster" it was immediately deemed too great of a light to use in my normally dark or dim work place, so now in a country unable to bear arms its now my home defense flash light 10/10 would recommend.

5 of 5 Premium light April 17, 2022
Reviewer: Eli Shermer from Lexington, IL United States  
This light has met all my expectations. It’s super bright, and has tons of features. It’s built solid and all the buttons feel great. I was a little worried it would get extremely hot but to my surprise the heat dispersion is great, it’s been warm to touch but never hot enough to feel like it’s burning. The flood light lacks a little bit of light in the center but overall not a huge drawback. If you are worried about whether the light is worth it, it’s well made and working in any sort of dark environment it will quickly pay for itself. Big fan of the lock feature and I’ve found myself switching between latching and tactical more than I thought I would. Very cool light.
