I made an important discovery while trying to use my cordless vacuum sealer. I tried three times to seal a jar. No success. I checked the rim to make sure it was clean and smooth. I tried a new lid. No success. Then I noticed a chip in the bottom thread on the jar (It was a new jar, too!) Since the vacuum sealer fits over the threads of the jar, it couldn’t get a good seal and vacuum the lid on. So, when you are preparing to vacuum seal jars, make sure the jar rims are smooth and clean AND check the jar threads for any chips or cracks.
P.S. This sealer does not make perishable foods shelf stable. Store vacuum sealed fresh foods in the refrigerator. Store vacuum sealed dry foods in the pantry.
