Once in awhile I buy the most useless and nonsenseical appliances known to man. Currently the one appliance I can do without is my food saver, which is this vaccum sealer type device which I have only used once, when I made some dried fruit with my food dehydrator to preserve the dried apricotts, peaches, and pineapple rings that I can get at the grocery store. Anyway, what useless piece of dust collection piece of **** appliance can you live without?
