Bests & Worsts Reviews from Amazon

I bought the 500 Lumen Duracell 3 pack at Costco. I like the fact that the flashlight doesn't drain the battery while in the off position. However each flashlight in the 3 pack is having the same problem where the flashlight will randomly turn off. Got to the point where the flashlight would turn off after 10 seconds. This problem made the flashlights undependable and useless. I will avoid buying this specific flashlight again until I hear that the problem has been addressed.
