Mainstays Canning Jar Lids, Regular Mouth, 12 Pack, Gold

Used the lids to water bath can some home goods, several of the lids buckled and bent during the process and did not seal the product. The sealant on the inside of the lids that buckled came off leaving a black substance on the inside of the jar

I'm old fashion about products. I prefer using Mainstay than the Superb. Superb looks cheap and if it don't seal my canning well then my preservers will rot. I recommend Mainstay.

they will not seal. I've lost a lot of food this year. went and bought Ball and every single one of them sealed. please don't purchase these and lose your good food like I did.. food you have sweated in your garden for. thanks Connie

I recently bought new jars. canned pasta sauce and none of the lids worked. had to re-can and used these lids. all sealed perfectly.

I bought these Mainstay canning lids to try because they were a bit cheaper than Ball or Kerr. BIG MISTAKE ! Over half of my jars did not seal. I have only had an occasional one not seal when I use Ball or Kerr canning lids. It ended up costing me more time and money. Oh, I am not a novice canner. I have been canning my garden vegetables and fruits most of my life and I am 76 years old.

As a seasoned canner, I can confidently say these are some of the worst canning lids I have ever used. I purchased the Mainstays canning lids expecting them to perform like any other standard canning lid, but I was extremely disappointed. Not a single lid sealed properly! I have years of canning experience, and I have never encountered such an unreliable product. Canning is an incredibly time-consuming and labor-intensive process. As a small business owner, I depend on quality supplies to ensure my products are properly sealed and safely preserved. After spending hours preparing and processing jars, discovering that the lids failed to seal is beyond frustrating. I ended up having to switch to Ball and FORJARS lids to get reliable results. I shouldn't have to waste additional money purchasing another brand just because these lids cannot perform their most basic function. The entire purpose of a canning lid is to create a proper seal. If it cannot do that, what good is it? I would rather spend a few extra dollars on a trusted brand than waste hours of my time, ingredients, and money on a product that doesn't work. Save yourself the frustration and buy a different brand. I absolutely do not recommend Mainstays canning lids.

Haven't used them yet but they are exactly what I expected.

These work as well as the expensive brand.

To date, I haven't had any issues with these canning lids sealing as they should.

Do NOT buy this brand. They do NOT seal!
