This should be on the cooking forum so I hope you read the directions that come with whatever you decide to buy thoroughly

. anyhow I have the Kenmore seal and save and it seems to be a duplicate to the food savor only a couple dollars less. Haven' t had any problems with it. It does the job it supposed to. However I have used different types of bags made by diff. manufactures and some seem have leaks in the seal either I made or the factory made so now I double seal everything. They to tell you to check their seals but if your paying good money for their bags you expect them to be good. Have Fun and start priceing freezers.
