The attachment just sucks the air out of the jar. You'll still use the normal lids, put the attachment on top and run the vacuum. The attachment sucks out the air (most of it) and leaves the lid. With the vacuum in the jar, the lid is held on very tightly. To open the jar, you just pry off the lid.
My food sealer has a "canister" setting that runs a longer cycle than it would it you were using bags. Yes, there is still going to be some air in the jar, but I think it's pretty minimal. The results for me have been the same, if not better, than the bags. I don't know if I got bad batches of bags, or if there were other problems, but sometimes, bags would lose a seal. As long as the rim of the jar is clean (no hop dust), the jars seal and stay sealed.
