Ball Kerr 150-Count Split-Type Metal Mason Jar Lids - Food Grade, Airtight for Regular Mouth Jars (150 pcs)

Some of them have been denting on the seal part causing leakage during the pressure cooking stage.

Used this product for canning garden stuff. For the money they are satisfactory lose one to material failure once in a while.

Just what I wanted.

Great value for the price. Haven’t had any issues while canning.

This was a good deal if you are willing to lose a few lids or jars that have to be reprocessed with another lid. They mostly seal very well, but now and then there is one that doesn't have a good seal. I bought 150 and lost about four or five of the lids from not sealing well. I figure for the price it was an acceptable loss.

Great value for the cost.

These lids worked for me for water bath canning. I have not tried them yet for pressure canning. I did have a few issues but they were operator error. The first issue is that I over tightened the ring and the lid buckled on me. I learned that it truly is finger tip tight! Also I had a couple that did seal, but realized later that it was because of my jar. I have missed a nick on the rim. Overall I am very happy with this purchase!

Very happy to have these, they are very hard to get a hold of these days. These took forever to arrive so I missed them for the canning season and had to make adjustments. Happy to have them now though.

I've sealed about 50 jars now with these without issue. The metal and rubber are thinner than on brand-name lids. While the quality is inferior, for a single-use product, if they seal who cares! Be sure to wipe down the jar edges with vinegar and you're set! They are less forgiving than a brand-name lid, but if your edges are clean they're great. Would definitely buy again.

I was very worried when I bought these lids but they exceeded expectations. Every one of them sealed so far. I will definitely reorder. Happy canning:)
