The USV20 is the best-value chamber sealer, and the one to choose if you also vacuum jars and canisters. Adjustable vacuum and seal times make it flexible. The warranty is one year, and the lid needs 17 in of clearance.

This review is based on Avid Armor's published specifications, independent test results where available (we name whose test each figure comes from) and owner feedback, compared against the other sealers we track. We'll add hands-on notes as our testing progresses.
Questions
Is the USV20 good for liquids?
Yes. Like all chamber sealers, it seals soups and marinades without pulling liquid into the pump.
