Use for years the fire balls to test any other lighter. A bag with 2.5kg reaches almost a winter season with us. By loose wood wool fibers outside they are highly flammable and by the size of burn the longest and provide enough heat to put any material on fire. Other fibreboard lighter can ignite heavy and are too small / not provide enough power for hard wood combustible, gasoline lighter are more flammable, toxic and it stink. To that extent, the balls are not the cheapest, but the best solution! Good price for this seller.
