Absolutely love! This review is for the 20 piece set. I love how I can just put the plastic lid on the same dish I cooked in to store left overs, then take it out to heat it up using a glass lid. They are great in the oven, on the grill, or the microwave.

Just be careful with sudden temperature changes. I have never had a dish or lid crack/break. I don't preheat oven and then put these in. I put them in and then turn on the oven. And with my grill, these dishes are not sitting directly on heat/flame. And I'm careful cooking at high temperatures. I don't cook over 450 in the oven or 500 on the grill. With the microwave, I let the dish sit out on the counter for a few minutes first.

I had two oval dishes with the glass and plastic lids, but it wasn't enough for us. Now I have two more in those sizes, plus more! I was not sure of what was included in the 20 piece set based on the description and didn't know if the photo was accurate. I took a chance and I am pleased that the 20 piece photos is accurate! I received all that!

5-Star Bases:
The mugs are great for soups/stews. You can heat those suckers up in the microwave to get things cooked evenly and the handle will be cool enough to hold and eat your food within a few minutes.
The round dishes work out best for cooling foods or eating out of when you have a solid surface or potholder/towel to not burn your hands.
2-Star Lids:
The rubber lids and plastic seals, while great for a solid seal (sometimes little leaks... like a few drops), it takes much effort to get them on/off. I doubt someone with any wrist/hand/dexterity issues would be able to get the lids sealed without a few cuss words being released in the process. Also, DON'T ever microwave the lids sealed. In fact, I recommend against microwaving with the lids on at all. They take on grease/oil, stains, and smells. The smell of savory things mixing might not seem like a hassle until you get a flash of curried quinoa in with your homemade chicken and vegetable stew.

Cleanup:
The bases clean up easy with hot water and soap. In fact, they are so smooth that boiling water wood probably be adequate to get them clean.
The tops... oh boy. I use vinegar/blue dawn under cold water to break up the grease (don't use this mixture under hot water unless you like the sulfuric smell of Hades). Then I use something to neutralize the vinegar (washing soda... be careful not to dissolve the seals on old drain pipes) before washing in hot water and dish soap. Or, as mentioned before, if you don't microwave the lid, hot water and standard dish soap are sufficient for cleanup in most cases.

Looks great. great sizes and a FANTASTIC value. I purchased the 10 piece set which I just received in perfect condition. I wanted another 1 1/2 quart piece and 2 more ramekins and saw the price would be $36. so I just repurchased this set. Great value for this set. I used to have these pieces and lost them - somehow - while moving several times. So glad to have this simple beautiful French White design in my new kitchen.

Looked good out of the box. Like real CorningWare. But when I tried to make a casserole today, I noticed the glass lid does not fit on the 2.5 quart dish. And the 2.5 quart dish was really the only one I wanted. I am not sure if it is a problem with the dish or the lid, but they do not fit together.

I thought the price was too good to be true. I seriously wonder if it is really CorningWare or a knockoff.

I still made the casserole and it seemed to cook OK. But had to make sure the lid did not fall off while baking due to the lid not fitting properly.

I love these!! I've been in search of some good quality cassarole dishes with lids. And when I saw the price on this set for $23, I quickly grabbed them. When i received them I was really worried about them being broken due to the fact it wasn't packaged well. But I'm happy with my purchase. The lids fit perfectly.
