Problem:Review_1: I didn't know what to expect when I ordered this, but I am pleasantly pleased. The unit fits perfectly into my Zippo case, and is easy to fill and use. Once in a while it won't light but if you blow into the flame area it will work the next try., Review_2: I think Zippo over charges and I wanted to try off brand. I must say I have been pleasantly surprised and my wallet thanks me. Don't get me wrong I love classic Zippo lighters however butane torches are clean burning and are great for EDC since they have almost zero odor. The torch also adjusts very nicely so you can fine tune your preference., Review_3: got for a christmas gift and i cant say how awsome this insert is i love that the fuel wont just evaporate the flames a bit big at first and had to urn screw as how the little lever wouldnt go over far enough but again no biggy awsome product i challenge you to blow this thing out, Review_4: i bought this product expecting it to last about a week, that was almost a year ago. i want to share just the facts: it plastic so don't go beating it aroundits a little small so some tape is needed to build it up and hold it in placeif you clean it right it will last for a long time, Review_5: I like carrying my classic Zippo and not tainting my cigars with lighter fluid. Much cheaper to get a Zippo and this insert than to buy a Zippo Blu. I also prefer the electric ignition to the flint wheel on the Zippo Blu., Review_6: I love the old style Zippo but was having difficulty with the standard fluid and carrying the lighter around in my pocket. This made it very convenient and it's a cool 'novelty' item. I still keep most of my Zippos original (standard insert), but it's cool to have a few of these with the 'butane' conversion kit..., Review_7: It did not fit properly. I then removed it and re-inserted original Zippo insert. To my dismay, cap of Zippo no longer closed properly. (Apparently, attempting to get the Thunderbird insert into the Zippo and close the cap caused the hinge to deform, rendering the Zippo unusable). Disappointing, to say the least!, Review_8: Thank God I found this. It works on Butane, and it will hold fuel longer than a week. Stupid Zippo, with their flints, and their packing, and their wicks. They make a version of this with a flint, do not buy that one, buy this one. It works great. Stay away form Z-plus.
Solution:
This butane conversion allows for the case of a classic Zippo to clean burning butane lighter. It allows for flame height adjustments and holds its flame well. It is a durable and reliable product that holds up well to wear and use. While this is not a licensed Zippo product it is important to note that its fit is not guaranteed.
