I have bought these several times.

I use my jars every day and store most of my kitchen goods in them and not original packaging. These lids are essential for your canning goods after you open them as well. I have put these in the dishwasher several times and there is no warping or distortion. One of the best things I like about the lids is that I can write on them with a Sharpie labeling the contents, directions,, expiration date and so on right on the lid. When I am finished I use a magic eraser to wipe the ink off and wash it . It gets a little worn but I really USE these lids. They work for me and are not for gift giving so a little dullness is fine with me. I have a bunch I use just for gift giving. I also freeze tomato sauce and soup in my jars and these lids are perfect for that. One thing that would take these ovver the top would be if they had some sort of rubber foam-ish kinda seal. Just for added security and freshness.

They're lids and bands, what more do you want?

I have a roommate who was very distressed that his lids and bands were starting to show excessive wear and beginning to rust because of it. I purchased this box to make it easier for him to let go of the few that really needed to be tossed out. The box remains unopened, but for the price, it's worth whatever psychological benefit my roommate experienced. I'd be happier still if he didn't snag my heavier stainless steel bands and actually used the ones I bought him, but at this point, I'm resigned to just buy myself more of the drastically more expensive stainless steel bands for myself after we part ways.

Lids fit seamlessly - tight seal

I was pleased to find these caps for my Ball jars. I actually don't use them to store pickled foods or jams/jellies. I often use these jars to store homemade salad dressing, sauces or soups or dry products in my pantry. I prefer using this plastic screw top lid (BPA free) opposed to using the metal ring & lid to store things in the refrigerator or in the pantry. The lid fits seamlessly. Just make sure you are screwing it on level & tightly. I've even poured some spring water into it, screwed on the plastic lid & took it on the road with no leaking problems. I need to purchase some for my wide mouth jars as well.

Five years of constant use and countless dishwasher cycles - they're all still holding up

I got both the wide-mouth and the standard size plastic caps and I use them all the time. Storing all kinds of things both in the freezer and in the fridge, and of course at room temp - these lids put up with a lot of use and abuse from me and five years later, I still have every single one of them. They all seal tightly, and clean up great in the dishwasher (top rack). I'd say I would buy again, but at this rate, I'm not going to need to :)

Plastic storage caps for canning jars

These work for storage; I use them on regular mouth Ball jelly jars for storing my Instant Pot yogurt. I haven't tested to see if these are watertight. They are a pretty good value at 8 for about $8. They do not include any silicon sealing rings, only the plastic screw-on caps. They arrived shipped only in a padded envelope, and the box was torn and crushed. As this was a purchase for my own use, the box's condition wasn't a big deal as the lids seemed undamaged. They need to ship them in sturdier packaging, though, as the lids could have been crushed, and the box looked awful . My star rating is for the lids themselves.

Perfect lids - no major leaking problems for me!

These are the best mason jar covers! I had read a lot of reviews on the cap that they leak? So when I got my first set I tested each one, and no problems. I use them for everything, sometimes I bring extra iced coffee to work, so I will fill a mason jar (not filled to the top but pretty full) and use this cap, I keep it upright in my cooler and don't have to worry about it spilling. I also use them for portions of cut up fruit, frozen soup (which is amazingly easy to bring to work) and I'm going to begin portioning more food in mason jars with this cap - just can't be the convenience and so easy to clean. Back to the leaking though, I would say 9 out of 10 times they don't leak .. there has been the occasion where a tiny bit of coffee has leaked out of the cap when it's in my cooler, but I'm not expecting miracles from these things, when I fill a mason jar with coffee and then it bounces around in my cooler I'm not expecting it to be perfect. Sometimes Ill just put a paper towel over it and no problems.

I use mason jars for EVERYTHING and I love these! I definitely prefer these over the metal ...

I use mason jars for EVERYTHING and I love these! I definitely prefer these over the metal lids, the metal lids rust and look bad. I use these for packing lunch, storing cut up fruit/veggies, leftovers in the fridge, and dried goods in my cabinets.One work around for these to keep from leaking, is to use the metal lid center peice and put that on first, and this on top. the rings are always what rust for me, so I just keep the center parts. Just use both together. I transport smoothies, and soups in these with no problem with that work around. When I use these for shaking chocolate milk for my daughter or protein shakes, you don't even need the metal insert first. It only leaks longer term, not just for shaking something quickly. Another tip is you can use permanent marker, or dry erase marker on top to label the contents, and it's also machine washable and very durable. I have these in both the wide mouth and regular sizes.

Here's the secret to making these water-tight!

These lids are just wonderful. They turn any mason jar into a perfect food storage container, they're easy to twist on and off, top rack dishwasher safe, and very durable. Unlike the metal lids, they obviously won't rust over time, and they are great for fermenting and storing pickles, as the sour and salty pickle brine tends to rust out metal lids very quickly. To the reviewers who complained that these lids are not water-tight, yes, that is true, but there's an easy solution. You know how the regular metal mason jar lids are composed of two parts? There's an outer ring plus a flat metal disc with a rubber seal for use in canning applications. Well, the flat disc with the rubber seal fits PERFECTLY inside these plastic lids. If you need to make your jar water-tight, just put the metal disc with the rubber seal on top of your jar, then screw the plastic lid over it, instead of using the metal ring. Voila! Nothing will leak. Although it would be nice to have a single water-tight cap, I find the discs with the plastic caps are still way more convenient than using the rings that are difficult to clean and rust quickly. I actually like that these plastic lids are not water and air-tight without the metal discs because it makes them more versatile. The fact that the plastic lids breathe works out well for pickling. I can keep the plastic cap on the jar while my pickles are fermenting, and it allows the carbon dioxide to leak out rather than build up and make my jar explode. Then, if I need to travel with the jars, I can just insert the metal disc, and the jars stay perfectly sealed.

no leak with orginal metal lid flat part inside and plenty of reasons to use.

I notice in some comments that people, who do like them, say these lids leak. For those who aren't familiar with this, many of us use them with the metal disc part of the mason jar lid inside. Then they are completely air and water tight. So one might ask, why get them at all if you are using a part of the original lid that rusts. I use them because 1) they stack much better, which is especially an issue with the regular sized lids but even with the wide mouth lids they just don't slide around like with the metal lids, 2) they don't rust so they screw on and off easier over time and 3) they are way prettier. I still use the original 2 piece metal lids for fermentation. I find the plastic ones, when used for a one week vegetable fermentation, smell like the fermented veggies so bad that it's tough to clean them, and sometimes I can't get the smell out of them at all, even when i have tried soaking in vinegar. There might be a solution I don't know about, and I don't know if leaving the smell in (like for using with the next fermentation) is unhealthy or not. I wouldn't use that lid for other kinds of food storage at any rate. But I like the plastic lids for everything other than fermentation. With the metal lids including the flat disc used inside the plastic lid, I use a mesh steal wool scourer, which easily cleans off the rust surprisingly well, leaving nice shiny metal.

Homemade Yogurt

These are great for making yogurt: After heating your milk in wide-mouth jars, uncovered, in a water bath on the stove on med-low to 180 degrees (takes an hour), then cooling on the counter to between 115 and 118 degrees (takes another hour); add a scant Tablespoon of yogurt to the jar, cover tightly, and set jar(s) in a cooler filled with hot tap water. Wrap cooler in insulated blanket. Check after 6-8 hours - should look jelled when you tip it slightly. Refrigerate. Next day: Put enough of your finished yogurt in a container in the freezer as starter for your next batch!
