I shopped around and this was the most flexible for the best price. It has lived up to our expectations: any size bag, from 1/4 cup to 2 gallon with the ability to use the vacuum for dry items or not for liquids. The instructions could have been a little clearer. I did have to read them twice before really getting what they said, but overall this was a great buy! Is this product review negative?
