I have no idea how well the Waring works, it appeared to be well made and solid. It is rechargeable so no battery replacement. I didn't purchase one, just noticed it was marked down, hand held, and was wishing my foodsaver was hand held. The Waring does not appear to have attachments for jars. I prefer to vacuum green beans in mason jars. If I were looking for an inexpensive vacuum sealer - this seems to be a decent buy.
