The top quality of Lock + Lock container inspires me daily. Countless hot dishwasher washes, constant use, decoction (eg when raw poultry has been kept in it), and so can this perfect product quality does not harm. Nothing warps, nothing is hazy, the lid still closes perfectly. Simply amazing! These containers are worth every cent - prefer to buy these high quality, than risk trouble with cheap food storage containers. I know a lot of brands, but Lock + Lock can not be beat. I can only recommend - the selection is huge, so I could always find the ideal size for the particular purpose. I take the cans for storage in the refrigerator or in the kitchen Shelf - in the microwave, I've never used, so that I may contribute no experience.
