Emily K.wrote a review of Princeton Tec Fuel 4 Headlamp - 70 Lumens on September 14, 2013
Familiarity: I've used it several times
The door to the battery broke off after using it for 2 months. It's useless now unless I duct-tape it shut. I always knew this would eventually happen, so I wasn't surprised when it did.
Other wise, great light. Used the blinking mode for bicycling. Would like it to have a red mode. Give it 3 stars for breaking.
