It isn't a Zippo. It may look like one, but it isn't one. It doesn't cost as much as a Zippo, and it isn't as windproof as a Zippo. Mine was manufactured by a company identifying itself as Jiantai, and they haven't done a bad job. I put fuel in, it lit first time. Like my Zippo then. My Zippo is now 13 years old and has had some use. I wanted a backup for when I go camping, so bought this.
The cam sometimes sticks a little, but that doesn't stop the case from closing. Looking more closely, and doing a side by side comparison, the dimensions are slightly different. The flint wheel centre pins look similar, with the Zippo appearing a little more solid.
The cam hinge pins and the hinges look identical. The hinges and mounting to the bodies look very similar.
Overall, the construction of mine is really rather good. For the money, it is very good indeed. The difference in windproofing was done using the tried and tested 'try to blow the flame out'. There wasn't that much difference.
BTW, use Zippo fuel. There is a difference in performance on my genuine Zippo twixt Zippo fuel and Perma. With Zippo fuel and flints, it is a first time, every time light. With Zippo fuel and Swan flints, first, second or third strike. With Perma fluid, second, third or fourth try no matter what the flint is. The flint as supplied with the copy lighter makes a veritable firework of sparks, just like a Zippo flint.
Overall, happy. Two lighters will take up less space than a lighter and fuel, and I can't abide gas lighters.
Edit:-
Just ordered a spare, and this time its branded as 'Dora'. Not that it makes any difference really as it is still a fairly well made, good looking lighter. Slightly different dimensions again, but still fits in the little 'Zippo' pocket on my jeans just fine. You really can't moan for the price.
