3 of 5 Bought for night rides on my bike. August 6, 2023
Reviewer: Randy Jorgensen from Omaha, NE United States  
I bicycle from work late at night and thought this would be great as a light for that.  The beam is very wide so it is great if I need to repair a tire or do any maintenance up close, and the lower settings won’t blind you at night.  I will say though, the button pushes are not intuitive to get to the strobe (which is the other reason I wanted it with me at night on the bike)  You have to turn it on then hold the button down to get to the strobe, but if you don’t hold it down long enough it shuts the light off. I am not a fan of the fact that you can turn it on with both a full press or a half press.  The half press is just too light for the turn on function and I am concerned that it may come on accidentally in my bag, so I turn the tale cap 1/4 turn to disable it.  So that is why it is 3 stars for me, to use it as a strobe I would need to turn the tail cap down, turn it on, and push the button down and hold it long enough to not shut it off.  Am I being too picky?

5 of 5 VNery Nitecore E4K 4400 Lumen EDC Flashlight June 12, 2023
Reviewer: Bruce  
This flashlight is the perfect size and length to carry in your pocket. I have many Nitecore flashlights and this one is my favorite for its compactness. 4400 lumens out of this little flashlight is amazing.
