Query: Works great... when you don't work it.

This is the 3rd one of these that I have purchased. One for myself, my Father in law and a friend. pretty sure I'll be buying more as the need arises. My father in law laughed at me because it "didn't work at all", so I took a look at it. I think he was trying to create a hurricane force wind to stoke the campfire with the way he was turning it! I had to take it apart to fix it, but then I realized how it works so well. There are at least 5 gears in there which means for every time you turn the crank, the inside wheel turns 50 times (just a guesstimate). Quite easy to fix too - and I added a little wd40 just to make it easier for him :)Very little effort is required to properly use this tool. The amount of wind that comes out is enough to stoke the fire and get the embers burning red hot.
