I purchased this popper to replace another popper that I used for 20 years.  My old popper looked similar to this one, but inside the canister, it spun the kernels to prevent burning.  This one does not.  Some popped corn comes out slightly burnt in the first round, and because the output is smaller than I'm used to on this machine, I need to go a second round, but it burns the popcorn more on the second round.  The second round is made more challenging because the plastic lid is too hot to touch to remove to pour in more kernels.  The wind power underneath the corn is not enough to push the popped corn out of the machine unless the user tips the machine to help it, which may contribute to the burning issue.   This was the best-rated popper on the market, but it is a sad replacement for my old popper.
