I have a FoodSaver I purchased probably 7 or 8 years ago, I can't remember the model number, but that is irrelevant since they discontinued that model years ago. I have had no issues with it and I use it at least every two weeks.
I'm not sure what I would do without it. I freeze casseroles by refrigerating them, cutting them into individual portions, freezing the portions and then bagging and sealing them...then back to the freezer
. Whole grilled, baked or smoked chickens work
great, too. Just refrigerate them first so the juices aren't so runny. (The juices will prevent the bags from sealing, as will most liquids.)
The only fresh vegetables I have sealed and frozen are green beans. I just washed and snapped them, allowed them to dry and sealed them. Worked great, tasted fresh when I cooked them.
Raw meat such as steaks work well, too so long as you pat them with a paper towel to remove most of the moisture on them.
There may be other good brands out there other than FoodSaver, but it is the one I have used and I know it is a good buy and will last for years.
