Brian S.wrote a review of Primus Power Ignitor Lighter on March 31, 2010
I've had mine for less than a year. Recently the igniter button would not consistantly spark. Now it will not ignite at all. It worked great when it worked. I would not expect it to last long. Always bring a backup source for starting a fire.
I emailed Primus, told them about the problem and asked about their warranty but I haven't received a response.
