Been using the Blazer pocket micro torch for over two years now, besides just a couple of scuffs on it the thing still works like new
On the same note, I do have a cheap $20 Xikar lighter that I've had for the same amount of time, however I haven't used it as much. It is still working just as great too though.
Guess it all depends on how pretty you want your lighter! Blazers aren't very stylish, kinda utilitarian. They have a HUGE reserve tank (I only fill it up about every 15ish cigars) and are very easy to view how much fuel you have left. Xikars are obviously a nicer looking lighter, however I find myself refilling it quite often (every 5ish cigars).
