The popcorn takes a long time to pop and leaves way more kernels than my old machine.  It also has a strange smell when it works.  I love that it's sleek and compact but wish it worked a little better. Boo.

1 Year update: Still working well and the strange smell cleared after a few uses. The amount of kernels left seems to depend upon the type of corn, but I still feel like it leaves more unpopped than my old machine. Increased by 1 star to 4.
