Super Cedar (http://www.supercedar.com) recently used the services of an unbiased 3rd party laboratory in the evaluation of our product and two popular competing fire starters. The results show clearly that Super Cedar is a superior fire starter, lighting easily, flaming for as long as 50+ minutes and putting off less visible smoke (pollution) than other tested brands. The study, along with pictures of the tests, can be found on the page : http://www.supercedar.com/test.html
