I have a lighter i like. It's not electric but have spark stone which finished. A friend of mine, told me, that he have some of them could bring me and fix the lighter.
It look's ugly because it's old and manufactured in the soviet union or Russia (i don't know).
As you can see it's says manufactured in 1990, store for 24 months. In means it's best before end 1992 :)
After some service works:
The lighter started to work again, with the stone that expired 25 years ago :D
Don't believe everything they type just for the marketing. Just to push you buy a new things.
