Here is a brief list of the cons of buying West Bend oil popcorn popper.• The popper should not be left unattended and you must shut down the popper yourself. There is no automatic shut down feature with West Bend popper.• The stirring arm is not bent but straight which can cause problems stirring the popcorns. It goes over the popcorns instead of moving the kernels.• With time some have complained of the Teflon coating wearing off giving a strange taste to the popcorns. So you may have to replace such units.Apart from these issues you need not worry about the quality of the popcorns produced. If you get good and fresh popcorn machine supplies you will get great popcorn in minutes.
