I may have gotten a defective unit, but the gear for the heating unit did not catch reliably with the gear for the motor.  This kept the metal sweeper inside the popper from rotating which in turn kept the popcorn from moving. This kept the popped popcorn from spilling out of the popper, leaving us with compressed popcorn in the popper, lots of unpopped kernels, and a generally un-fun time.

Too, when it was time to clean (and return) this machine, I did not find clean-up easy.  Lots of kernels and popcorn bits jammed into nooks & crannies in the bottom of the box.  

Can't recommend this one.
