I've been using FoodSaver for years. Meat, chicken, pork, etc tastes as fresh as it would if you bought it from the butcher. Sometimes getting the FoodSaver bag sealed and then vacuum packed takes a little maneuvering and other times I have to start over because there was still some air in the bag. All in all, I love the product whether I use it to put frozen, uncooked food in it or even precooked food. It still tastes as fresh as if you had just cooked it.
