Lid on medium dish doesn't fit well

This product is ok if you're not looking for high quality.  The lids don't fit very well and the carrying case is a bit cheap.

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.

For further assistance, please contact our Consumer Care Center at 800-999-3436.  Representatives are available from 8am to 5pm, EST, Monday through Friday, and will be more than happy to assist you.

Sincerely,
Monica

There is too big of a gap from the lid to the food storage area, if this goes in a lunch box then it cannot be turned sideways or all the food will mix...I'm returning the one I bought for my son.

I bought this because another item fits inside it perfectly. The quality of the metal is good.
the top doesn't fit well enough.
I have found better cookware solutions for about the same price, Texsport being one of them.

Bought these for my new cookware set, unfortunately the lids do not fit. As other have said, best for lids with circular tops, not the handles they tend to have now. I will use it for other lids, so it works, but am still facing the mess of new lids :).

I bought two sets for my mom who desperately needed new tupperware. She wanted ones with venting lids because they would be able to go into the microwave which she does often.  Being Pyrex and bet having some of there non-venting glass Tupperware  (but still too many plastic ones) for 20 some odd years I had very high expectations. They seamed nice, but it is the lids that are the problem. They either seal or dont, I can take one lid and it will fit the container it was meant for, but the duplicate one it will not fit, it just slides off. The vents  buttons don't open or close well at all, almost like the clasps don't fit the buttons. It just seams quality control missed on some of them. The lids that did fit the containers, even when pressing the botton to release air, we're very hard to get off, I'm pretty strong, so my mom had a terrible time with them. I just wish they would have spent more time on quality for the lids. She tried for a month or so but did have to return both sets.

The lid does not have a tight fit. It keeps popping open on its own. I couldn't trust it to keep my flour safe and dry, so I'm using it to hold odds and ends. I can't recommend this item.

I purchased this lid to replace my damaged lid.. This lid does not fit like the 4 lids that came with my original Pyrex set.. It practically just lays on top where as the original lids actually fit on and stay on.. I know they're not supposed to be a tight fit but, the lid should not fall off when the dish is flipped upside down.. I am quite disappointed with the quality and would not recommend this replacement lid..

It's not quite as big as my old one. It doesn't quire fit an entire bag of cat food. Also, the smaller spout gets in the way of using the hinge lid. Needs a little rework on the tolerances.

It's hard to give a review on this. The quality is nice, it works well with my convection range, it is absolutely the perfect size for a pot or rice or other small things. BUT my complaint is the lid. I'm OK with the glass, but the moisture and oil/butter collect under the rim. It is very hard to dry and keep clean. I have to take a paper towel and clean up under the rim to get rid of the moisture that collects there. Rather a big pain, but I will probably not look for a replacement as this particular size is hard to find in something other than a set. At least in convection cookware.

Love the lids but the spoon isn't very efficient. Seems like wet food just gets stuck in it.  Not a well thought out product design.

Dish is nice for the price, but cover does not fit over Costco 1 lb California European style butter bricks. Just using the bottom plate.

the lid is not air tight, which seems like it should be for a braed canister.  It needs to have a rubber ring around the edge.

I like the product, but did not realize when I ordered that my lids all have handles, not round knobs, so they didn't really fit well. I gave it to my mom.

The only thing I don't like about this dish is that because the lid handle is on top, you can't put stuff directly on top.

Not very happy the keeper lid does not fit the bowl which defies the purpose. I can spin salad but then cant seal it

Dimpled top for handle takes room up inside. Lid a little loose. Will try it out soon. I put it in our pizza oven outside after baking to cook a chicken.
