It works!
It is so easy to seal a lid on any mason jar. I wish it included the hose to be able to extract air from plastic bags manually without having to use an electric bag sealer.

So easy my 5 yr old loves it!
This has been a life (and money) saver!! My grandbabies love to snack on fruit, but a lot of times not in time for it not to go bad. I purchased this and taught my 5 yr old granddaughter how to use it and she seals her grapes and strawberries back up by herself after she gets her snack out.
