Absolutely fantastic popcorn popper. We feed our wildbirds popcorn and have been spending about 20 bucks a month for microwave popcorn (the cheap generic one). @.25 per 5 cup bag, that amounts to 5 cents per cup. This device pops 10 cups for 8 cents, or about .8 cents a cup. Over time this will save us a lot of $$, not to mention that this allows us to pop corn without all the additives, salt, oils, etc, much more healthy for the birds.
We have been looking at air poppers, but they are expensive and messy to clean. This popper rinses out in the sink and collapses for storage, though it will not see any storage util the birds fly south for the winter. I hope it will last a long time, but at 12 bucks, we can always buy another if it finally fails.
