I keep reading all these posts about how good they are but my experiance has been a quite different. I bought one and a friend of mine bought one, from diffrent places. Mine would work but it took between 50-100 time of pushing the ignitor to light the thing.And of course after doing this several times it just locked up and would not spark any more. My buddys never would light.I just read in a post here that someone had problems at altiude. So maybe thats what was wrong with ours, we live in Colorado.Guess I'll have to stay with the spray (deet).
