5 of 5 E4k review August 3, 2020
Reviewer: Justin Skultka from Missouri  
I got this to replace my mh20 charging the battery is nice . Definitely bright and tactical as in will shock someone’s eyes with the brightness in the dark. It is small 4 5/8” long diameter of light head 1 3/32 “ across
I ordered an extra battery and I ordered the charger box hoping to charge my batteries faster.the only complaint I have is that the case for extra batteries is for 18650s it should be for another 21700. I use the case for my other flashlight batteries. Overall the light is so sweet I still give it a 5/5 nitecores quality is top notch.if you’re looking for tactical and an everyday carry get the E4k/ sign up for emails and get 15% off also.4400 lumens .

3 of 5 Great products! July 23, 2020
Reviewer: Jon L from SPRINGFIELD, MA United States  
I love the quality of Nitecore flashlights. They seem expensive until you own one and then the price is the last thing you think about.  My 1 and only complaint is that not 1 of the 4 products I own have the same push pattern for operation.  It's very frustrating and I don't know why everything has to have a different pattern. Besides that, quality is top notch.  Would be 5 stars but the pattern thing is very annoying. Not an issue when you only use 1 product though

5 of 5 My second E4K July 12, 2020
Reviewer: MKT GUY from Flemnjinnnnnnnnngton, NJ njStates  
Rule #1 - read the directions
Rule#2 - enjoy the power of 4400 lumens in the palm of your hand. I've been using the E4K for over 3 months now and the battery life is awesome, the various functions are usable and the brightness surprises everyone that sees it.
