Having received a few glass containers through supermarket promos, I was converted. These can go from freezer to oven (without the lid) to fridge to microwave and no matter what you put in there do not stain, or get those unsightly white marks. Much more hygienic and the best feature is that they go in the dishwasher. Most genuine Tupperware does not. I’d read in the reviews that sometimes the lids are difficult to clip, this is only when it isn’t on 100% - so if you find the clicking of the lid tough, just lift and realign it. This set has the perfect combo of shapes and sizes. Some bigger and some smaller with a few in between. There has been nothing so far that I’ve not found the right size for.
