This food vacuum sealer machine works well, and the included bags do not leak. I have used it to vacuum seal both meats and fruits, and each if those items are still vacuum sealed in my freezer without freezer burn.
The machine is easy to use with the included bags (or any vacuum seal bags/rolls). I have not tried the canister attachment, as I don't tend to store items that way. It does not feel as heavy-duty as other brands, but it performs just as well as the others I have used.
The advertised price of $499 is a bit ridiculous (other similar machines cost MUCH less), but it works. (I did buy it at a reduced price.)
