5 of 5 My goto EDC for flashlights April 16, 2021
Reviewer: E ScoScotttt Espedfbdsfnbsnshade from fdgnLas Vegas, NV United States  
I really like Nitecore and have 7 different flashlights from them at this point.

High-quality items that function well and last for years. I haven't had one fail in the past 5 years.

5 of 5 Big power in a small package! April 15, 2021
Reviewer: Mark C from Shasta Lake, CA United States  
This little flashlight is incredible. It’s very bright in turbo mode naturally, but even on medium or high it’s quite  bright. The beam is spread out nicely, giving a plenty wide swath of light. As a comparison, the MH12S flashlight has a much more focused beam, allowing me to see to the front of 53’ freight trailers if I need to, even with less than half the lumens of this light. This light just gives a much more broad illumination.
 As for the quality, it’s top shelf, period. Enough said.

2 of 5 Incompatible sizing March 19, 2021
Reviewer: Use a ruler next time  
Its made to fit Nitecores own battery, but is too long for an actual 21700 that it advertises as such, worst of all it doesn't include any sort of adapter for 21700 batteries. Measurements are meaningless if you don't use them as such. If your flashlight only accepts 75mm batteries don't advertise it as a 70mm.
