Query: Overall good performance

So far the Food Saver Regular Mouth Jar Sealer has worked great. Just get your jar, put on the canning lid, and then put on the jar sealer. Connect the jar sealer to the food saver with tubing and turn on the food saver. Last put the canning ring on. I have not had any issues with it not sealing. The only negative is the blue rubber piece comes off sometimes, but is so far has been easy to put back in.
