These aren't the cheap knockoffs currently lining hardware store shelves. Ball, Kerr, Bernardin, and Golden Harvest lids are all the same lids sold with different designs and in different areas.
I've canned a little over 8 dozen jars of beans and 20 something jars of red onion pickles in the last week without a failure. When I do I have the occasional jar that doesn't seal, the problem is almost always a small dent or twist in the band that I missed.
One word of caution about Golden Harvest that has nothing to do with the quality - the jars are metric and the middle of the jars are a little wider so they don't fit quite the same in canners.
