After watching a number of videos on YouTube, I decided to purchase the Yukon Ultimate Bundle for additional heat (to my gas outdoor fire pit) and ambiance in my backyard.  Once lit, it took about an hour to get to the “sweet spot” that was promised.  (Not surprising considering the amount of wood it holds). Beyond the appeal of virtually no smoke and good heat output, the flames appear to be in slow motion which is really cool visually!  Great purchase!!!
