I have used the FoodSaver products for several years and and on my second vacuuming unit.  I like to buy hamburger in 10 lb increments and then freeze with the food save rolls cut to the appropriate size.  I also buy whole pork loin and cut it into chops or roasts and freeze with my foodsaver products.  I also like to marinate meats with the vacuum sealed containers for grilling.  I would never be without my FoodSaver!
