The lid doesn't stay on tightly with the end closures.  Other than that they are okay.

Loved it until the lid wouldn't stay closed any longer.

The lid fit snug into the cup but the moveable cover on the top is very loose.  The lids were bought as a gift and they haven't been used much so not sure if how well they work yet.

I think this and the associated container are lid, but it is not a "snap tight" seal, only adequate for casual use. I bought one set to try it out, and will keep it, but I am going to upgrade to some of the more slightly expensive commercial products also available on AMAZON.

I expected the lid to fit tight (for camping)  but if this tipped over the lid would fall right off.

It is not air tight.... The lid has all straight edges but the porcelain ends are curved so there is about an 1/8 gap on the ends.  Doesn't make an air tight seal.

The lids don't fit the containers very well. I'm not always sure that they going to hold everything in.

It is difficult to get the canisters to seal tight. The metal clamp piece you have to get just right in order for it to close properly.

Well, the pan is great, of course. But, I got this because I wanted the lid so I could travel with a casserole over to my friends house. The lid doesn't really fit that well, so it's on but it doesn't stay sealed for some reason. Maybe it's too loose, or something.

The lid doesn't go all the way down and its hard to get out if its too soft, otherwise, really pleased with it.

The lid doesn't close immediately, I have to wait for it to close slowly and gradually... Sometimes I wonder if it closed well because I never hear any snap or cling etc

the issue is that lid doesn't have a fixture to stay open, could shut close in wind. also it's not safe to close the lid while cooking; the plastic latch would melt.

I like the design and size. However, the lid does not easily shut or open. Force has to be applied in order to open or close it because the shape of the lid does not quite align with the shape of the base.

I have this set and some lids nearly fall off from setting them on their sides.  I got a replacement lid but it was worse then the original.  Here is the response World Kitchen LLC sent me:

We are sorry to hear of your dissatisfaction with the replacement cover and apologize as we did not realize you were looking for an air tight or leak proof fit. The standard storage covers are not air tight or leak proof and we currently do not offer this type of cover.

I love the lid that covers the screen.  I no longer make accidental calls when I put it in my pants pocket.  However, the lid does not stay shut when I lay the phone down on the desk.  The stiffness of the "hinge" makes it flip open.  Otherwise, it serves my purpose.

Super cute design, and easy to clean, but the lid doesn't stay on. I have to use rubberbands to make it work for me.
