I have had a FoodSaver for a long time and have used nothing but FoodSaver bags. I bulk buy and find the rolls to be most helpful for me. I recently cleaned out my upright freezer and found a steak I had sealed in the bag dated 2016. The steak looked like I had just bought it and when I cooked it, it had no freezer burn and tasted just as fresh as if I had just bought it.
