      Hmmm... Best of October 24, 2020

      The flashlight is small and handy, but heavy enough you don't loose it, looks nice, works fine, floody homogene light with frosted Carclo Optic and neutral tint with XP-L HI V3 3A 5000K, good to find in a dark night with trit in the tailcap.
      Fast international shipping (one week).
