We are very satisfied with this item. You store a roll of bags inside and pull it out a little to seal, than cut it, stuff it with stuff, and seal the other side. The storage/seal beginning step worked slick. Only downfall was when setting up there looks to be a metal tape strip over the sealer and we weren’t sure if that should come off and very little in directions about setup. Came to the conclusion you should not take that off.  Two different sizes of bags included. Far more than I was expecting.
