I have one similar to this. I like it as it puts out a very hot flame. BUT, a few of the drawbacks are:
1. The flame is not very high, and it is hard to light things like a stove, lantern (Impossible), or even a bigger candle, because you have to get the flame so close. (If you light a small stick, paper etc.. you can get around that)
2. The butane supply in these things get used up FAST!!!!! I used up the initial supply just playing with the dumb thing for a week. Then went and refilled it. Which makes me wonder if it's a good choice for a survival lighter, as you should probably carry extra butane.
It lights everytime, and is a cool little design, but after I got back from a camping trip with the lighter, I just threw it in my truck as an emergency lighter. I Prefer something that actually has a flame of a couple of inches.
Just my thoughts. And I didn't pay that much for mine at a local store somewhere around here, I don't remember, but I do see them form time to time.
