Just got my ranger today. I have to say this thing is pretty awesome. I loaded up and lit it. It ran for just over 25min on small ash wood kindling. Had it going for about an hour now. And its pretty mesmerizing. Throws out good heat once the secondary burn kicks in. I think I got my new truck fire pit. Good size for a few people to stand around at the end of the day.  It does burn quickly but that's what I was looking for.  I had my doubts but its pretty legit. I'm hooked.
