I feel I’m ALWAYS writing reviews with the same common theme:Read the item description IN FULL , and make sure you understand it.READ the instructions when you get it.I received this in an excellent box, WITH battery, and it works great.After reading the instructions, I tried it out almost every morning for 3 weeks, it held its brightness, I spent no longer than 2 hours of CONTINUOUS use with no problems. It’s just as the item description stated.This is a well constructed light, it’s worth what I paid.NOTE: ANOTHER point I’m forever passing on is if you are expecting filet mignon at a Big Mac price you just aren’t going to find it. Also, I am always reading reviews where folks get an inexpensive piece of equipment, then state “it’s not as good as their high dollar such and such”, well if you have the high dollar item, why are you going cheap now?
