Connected to my low end vacuum unit without problem. I am using it to vacuum pack pint jars of powdered green onion. This is a very fine powder. The kit sealed these jars perfectly. This vacuum kit has solved a huge problem for me. I can see this kit being used for many other vacuum storage projects. I highly recommend it.

I recently received my vacuum seal kit for my mason jars, and used it immediately!! I love it! The process was SO easy, and now I want to seal several dry pantry items in my jars! Such a great product!!❤️

Works 75% of time, can't expect much for the price. Works in a pinch and why I purchased it. Fast delivery and will order from you all again.

The tubing does not fit tight in the pump opening. I can get it to work if I wrap a small piece of rubber strip around the tubing end and carefully fit it into the opening, but it doesn't always make n airtight fit.

I somehow got 2 of the same orders, emailed you when I saw the charges. Asked if 1 could be canceled. Response said I would hear back, didn't. I then received both packages, and emailed again off the link for return it said I would hear back to process refund and have not heard back from you, so was charged twice received 2 orders and can't seem to get the refund and return started. Will not order from you again.
