I've had a foodsaver (professional) for about four or five years. I pretty much seal up everything I freeze and it does keep everything fresh. It is especially good for freezing cooked butt and brisket. To serve, you just put the bag in boiling water and serve.
There are only a couple of complaints. They are exorbitantly priced for what they are. And the price of the bags is exorbitant (ie. it runs 50 to 75 Cents per pound).
Secondly, the bags are rather flimsy-If you have a bone that is anywhere close to sharp, it will easily pierce the plastic and you have lost your vacuum seal.
Thirdly, you have to be very careful when you make a seal that the plastic is dry and does not contain any food matter at the point of the seal. Otherwise you will loose your vacuum.
The foodsaver is in a catagory where much could be improved through competitive economic circumstances. There are a few other products out there but represent no real competition. If there was real competition, price for the units and bags would be 1/4 to 1/3 of what they are now and the products would be much better than they are now.
That's my two cents.
