I just tested some cheap peanut lighters that I got off of Ebay for a few dollars. They were also sitting around for about 2.5 years. They lit up just as good as the mini peanut lighter I bought from County Comm, and they have low quality O-rings on them. So, go figure. The peanut lighter design, in general, is just a winner I guess.

The only difference, as far as I can see, is the cheap shell of the lighters from Ebay. They look like some sort of cheap alloy that will bend if you step on it really hard. In contrast, the stainless steel shell from County Comm can allegedly handle a fire truck driven over it. I have not tested that, but the County Comm stainless steel shells are obviously higher quality. To me, the twelve dollars extra is worth the better shell. After all, the main reason I have this lighter is to have a bomb proof fire starter on my key chain.
