Terrific flashlight. I just wish that quality control was better. I had to return and re-order about 5 or 6 times (ordered 5 lights). Great flashlight and self-defense item when ordering the extensions.

### ⭐⭐⭐⭐⭐ 







  
  
    Was skeptical but well worth it
  

*by A***R on Reviewed in the United States on March 19, 2016*

I bought this thinking the flashlight wouldn't come with it but it did with the capacity for 3 18650's. And watching the reviews for this item made me scared it might not fit.  But after attaching this bad boy of a piece to my already extended flashlight, it now takes 4 battery's and fits tight and firm.  Now I have a mini baton 😊 / bright ass flashlight

### ⭐ 







  
  
    Not the proper extension for the light it claims.
  

*by K***R on Reviewed in the United States on March 14, 2016*

Same issue as other posters. Threads on extension are too coarse for the threads on the flashlight.  Does not screw on far enough.
