Query: Perfect Popcorn

Makes great popcorn. No more Jiffy-pop or microwave popcorn for me. I have not yet experienced some of the problems assoicated with the plastic gears melting noted in the other reviews. I keep the flame on medium to mediam-low to make sure the pot does not heat up too much. But I can see it becoming a problem if I set the flame too high.How much would it cost the mfg to make the gears metal instead of plastic? I don't think that much more (and most people would pay a little extra for the metal gears, I certainly would have). So because of this, I gave it 4 stars instead of 5.
