As I cook many dishes in bulk, i.e., soups, chilis, stews, I was looking for the most economical and vertical way to freeze excess. These containers are perfect for the job. They are sturdy and don't crack with temperature change. I don't throw them from freezer to microwave, but other containers crack just sitting on the counter from the freezer. These hold up. Also, I find that on the top rack of the dishwasher for lids and containers, they maintain their shape and don't get funky.Will order again!!
