I have had a Food Saver for many years and use it for all meats, poultry and seafood if I know they
are going to be frozen for a time. No more freezer burn and they keep for a very long time. I use it for all cheeses, never have to toss moldy cheese away now, as I keep a lot of cheese in my fridge. Also, nuts, home made applesauce for my freezer. home made pasta sauces too. Blackened Hatch chilies that I do in Sept. and use all year long. So many uses. A real biggie is that you can reseal all your chip bags, and those papery bags that cereal in packed in, inside the boxes. Reseal candy bags, too.
You must keep your Food Saver out if you are going to make use of it. No one wants to keep getting it in and out every use, and I use mine several times a week, I keep it on my laundry room counter. Sometimes we use it more than once a day.
We also reuse our Food Saver bags several times after the initial usage. They are washed with hot water and dish soap inside and out, and hung to dry above my laundry room service sink. Sure saves a lot of money.
