I have a foodsaver; actually two of them. When I called the company for new gaskets, I ended up buying a new "gamesaver". I use mine probably once or twice a month, and go through several rolls of packaging during the year. When the sweet corn is harvested, I use it to put up a couple bushels at least...also lots of hamburger and other specials.
My only complaints are as follows: The packaging material is about $20 for two 11" X 16ft rolls...so if you're thinking of saving a lot of money, you have to factor this in. Secondly, it does not work well on wet foods. I have put the corn in the freezer overnight and package it the next day. This works very well, and the vacuum stays very well. Thirdly, I found that the package sometimes loses vacuum, so I always double seal mine. Lastly, mine is the model that sits flat. In order to get the package to seal more easily, you need to place the package on a book or some object that brings the bottom of the package up level with the lid...otherwise you have to use a bit more of the packaging material. They have an upright model, but have no knowledge of it one way or another. I am reasonably happy with mine, although sometimes I have to wait between packages for it to cool down.
Seems like we had a long thread on this subject a year or so ago?
