ZWILLING Fresh & Save 10-pc Medium Vacuum Sealer Bags, 1 Gallon, Reusable Sous Vide Bags, Meal Prep

So far, so good. I needed a new pantry storage system and having looked at several, I found the Zwilling system to be the most diverse as far as capability goes. The vacuum pump is very easy to operate and in most cases it is clearly visible that air is being removed from the storage container. Caution should be exercised as it can be engaged to vacuum without being on a container. I've only recently started using the system, but it appears to be holding the vacuum quite well. Time will tell, but I've made a substantial investment in the system to improve longevity of pantry goods and deter any insect infestation that can occur in other types of containers, including the original packaging.

These bags are the best for really keeping the air out. The seal is tight as long as it’s closed properly. The only negative I have is I wish one side of the closure would have an extended lip to grab when opening them from a sealed position. Not a big deal, it just would be nice for my arthritic fingers.
