Review on Illuminate Your Path with the Black Diamond Revolt Headlamp: A Powerful Lighting Solution by Jonathan Brendemuehl

Used about once a week and worked very well for about 6 months, bright light and comfortable oh. Stop loading! So, took out batteries, even tried standard AAA batteries, still doesn't work. Noticed the loose middle battery and found that the middle battery had no electrical contact but moved freely between the contacts on each end. There is no spring tension. I bent the spring (-) and the light didn't work for long, then it was too loose again. The spring contact metal is soft and will not hold the correct shape. The only way to use the light is to place a small piece of aluminum foil on the (-) terminal to press the battery against the terminal. Too late to return to Revane. I will not buy again.
