these bags work great for sous vide, but they are not really reusable. The residue in the bag (example: fat from the meat) does not wash out so would not be sanitary to reuse. As long as you are good with using once, they are a good buy.

These are the biggest piece of crap you can buy. Just get a vacuum sealer or bags that has a a better vacuum port. 9 out of 10 bags the air port was blocked and wouldn’t function.

Works pretty good. Used these for a while before I got a nutrichef. Good for souls vide.
