These look great, don't hold stains or odors, and generally appear to be high-quality. 

But the plastic actually cracks very easily. The smaller containers seem to have shorter shelf lives than the larger containers. First, the lids form large singular cracks that let air in. Several weeks or months later, the bodies form cracks that gradually wear down and become openings for fluids to leak out.

These are such trash containers, and I hate that I bought enough for a week's worth of meal prep. I've already had to throw out four because they're completely unusable, while the remaining ones are gradually becoming useless.
