Super nice PowerXL Duo nutrisealer seals food in 6 different ways, including vacuum, valve, food bags, snack packs, containers & bottles. I mainly use the vacuum bags for buying bulk food, I haven't used the other type yet but I'm sure I will. The sealer is ready as soon as you open the box, it's super easy to use and comes with everything you need to get you started. This is such a life saver, now I don't have to worry about freezer burnt food.
