Review on Zippo 121503 Fuel Canister by Jason Dennis

I like the idea, the execution leaves a lot to be desired. Here are my constructive criticisms: 1) The size and capacity are perfect. 2) The overall design and aesthetics are great. 3) The "strip" around the canister needs to be knurled, it can be difficult to unscrew the part you want to unscrew. (i.e. you want to unscrew the cap to refill the lighter but end up loosening the bottom like you're refilling a canister.) 4) Aluminum is too soft for the threads used, mine tends to make cross threads in the bottom. Now I have to be very careful not to overtighten it after refilling and sometimes even when I'm sure I've tightened it right it gets crooked, the inner rubber seal inside pops open and my liquid evaporates. So now I have to be careful not to drop it between uses (I keep it in my toolbox at work, not on my keys or in my pocket).
