    1. Excellent Product  star rating

      Posted by Floyd on Dec 19th 2020

      I have now used a lot of these oxygen absorbers and none have failed. Even in these pandemic times where shipping is slow and products can be hard to get. PackFresh has provided excellent service and super fast shipping.

    2. Work great  star rating

      Posted by Unknown on Sep 10th 2020

      I’ve used pack fresh oxygen absorbers for several years. They work great. Keep my food perfect

    3. Good product  star rating

      Posted by Emaline Spangler on Jul 31st 2020

      Used them to dry can rice and cornmeal in mason quart jars.
      Every jar sealed within 12 hours.

    4. When only the best will do!  star rating

      Posted by David Melamed on Mar 12th 2020

      I spent thousands on my Freeze Drier and thousands more on the food I store. Why would I want to use a cheap and un-reliable Oxygen Absorder.

      This product is top quality and more importantly I can trust it!

      Did just what I needed. Very confident in this product. Thanks

    6. Fabulous Product and Company!  star rating

      Posted by Chris on Jul 5th 2019

      This product performs better than expected. I use the 300s in my medium size mylar bags and the 500s in my larger bags. If you shake down loose items and tamp down fine-powdered product as you fill, just one of these babies will vacuum pack tightly. I'm impressed. And I also appreciate the company's fine service and readiness to answer questions. Happy Camper.

    7. Great product  star rating

      Posted by Unknown on Feb 2nd 2019

      We have been very pleased with this product. Highly recommend this for use with long term freeze dried food storage.

    8. Yes! They work!!  star rating

      Posted by Missy Hinegardner on Feb 13th 2018

      We use OAPs for our dehydrated nuts/seeds. They keep them fresh and crunchy. We soak/dehydrate in the winter so we can go out and have fun in the spring/summer/fall. All of our nuts/seeds stay fresh and healthy for many months as we rotate through them. They are also a great insurance policy for fresh items should we get hit with a winter storm--we are prepared if store deliveries are interrupted etc. PackFresh has very helpful information regarding use etc. Worth your investment!

    9. very reliable  star rating

      this is the second batch of scavengers I've been using, and so far no fails. Great product, great price, well packaged and fast shipping. Very happy with it

    10. Great and Easy to use  star rating

      Posted by James Howell on Apr 6th 2016

      These worked great for dried canning. It made the job so easy that now I have a nice little stash of beans, rice, instant potatoes, noodles and powdered milk. In a few hours all of my Mason Jars were sealed
