1 of 5 Not so good Good and not so good. E September 19, 2021
Reviewer: Kyle Colenbaakyk from Lexington, IN United States  
Worked great for 9 months. The switch quit working. Support is next to nothing. Now I’m left with a paper weight.

5 of 5 Nitecore E4K 4400 Lumens EDC Flashlight August 27, 2021
Reviewer: SteStevephen Denlinger from Hereford, AZ United States  
Nice unit. Performs exactly as described by Nitecore. It's relatively small and unobtrusive. I ;much prefer the side thumb button over the end button. That's one of the main reasons I ordered this unit. I particularly like that it will remember your setting choice when you turn it off and back on again. I also like that you can go to super-bright in an instant. All in all - AAA+++

4 of 5 Bright and conpact July 1, 2021
Reviewer: es Hughes from Portland, OR United States  
The E4K is a very bright flashlight. It is compact and we'll constructed. The detriment is that it heats up quickly. One would not be able to use it long before it would start to burn their hand. Also, not sure how to recharge the battery. Will likely have to purchase another charger for the oversized battery. But this unit is as bright as flashlights 3 or 4 times it's size.
