I've gone through several 45 and 90 degree lighters, and I should have paid disposable prices because they all stopped working after awhile. Usually it was the spring which triggered the electronic ignition, or the jet clogged.
My Zippo Pipe, on the other hand, has been nothing but reliable, and it is also the best solution for keeping the char off my rims. Even with a higher flame, outdoors in the wind, that horizontal ring (you turn it horizontal to light your bowl) keeps the flame above your rim until you suck it down, where it cannot touch anything other than the tobacco in your pipe (unless you move it off-center or allow that ring to contact your rim). It's also powered by naphta fuel, which I think burns cooler than butane.
