Bests & Worsts Reviews from Amazon

These inserts are made in China, and although they say "Made to Zippo Quality," they certainly are not. My first one worked okay, I filled it with Zippo brand butane and it worked for a few days, then it stopped, so I filled it again, following the instructions. It lit maybe twice, so I turned the adjustment screw on the bottom for a larger flame and it produced a flame the same size as before. I'd have to keep adjusting the screw higher and higher until it reached its maximum, and it stopped working completely. I returned it for an exchange on the exact same item. That one was great! After the first fill up with Zippo brand butane it worked flawlessly, the first fill up lasted longer than all the times I filled the first one combined. Then came the first refill, and it stopped working completely, you can hear the butane flowing and see the spark from the ignitor, but it won't light. Tried turning the adjustment screw and it won't budge, it's almost as if it got torqued down too much in the factory. The product idea is great, but the quality control sucks.
