4 of 5 E4K January 29, 2023
Reviewer: David J Ramsden from Brooklyn, NY United States  
Very bright and seems well made. Switch is a little confusing at first. Read the instructions and you’ll be good. Not a reason not to buy.

5 of 5 E4K January 13, 2023
Reviewer: Jed from Indiana  
Very nice flashlight at the perfect size I was needing. I do a lot of woods hiking at night with a female friend. I was looking for a light that had multiple brightness settings easy to access, small enough to carry in any pocket, long run times on the lower settings to watch our step on the trails but still had an extremely bright turbo setting to buy some reaction time in a defensive situation if needed or taking a quick look far down the trail. Very good light for checking out those night noises in the backyard too.
E4K along with a spare battery is perfect for my needs.

I have been looking for an EDC flashlight for some time now, but my search is finally over.  After several purchases that left me unhappy, I have found exactly what I've been looking for.  Very bright and the perfect size.  Love it!

5 of 5 Great Self Defense December 28, 2022
Reviewer: Brent NevBrent insB from Grand Rapids, MI United StatesMichigan  
I bought this for my daughter who walks to work (about two blocks).  During the winter months it's dark when she goes to work and when she returns to her home.  This is a great non lethal self defense light that is small and light weight.
