Mine is very effienct, but then I do have the very dry high desert air to help. I often use frozen foods that I buy during bulk sales and the same buy during good produce sales. When you consider the cost amd shipping charges buying commercial canned dehydrated products you are bond to come off ahead. you will also have the advantage of knowing you are buying dehydrated food from China.
