Review on Convenient 4-Pack: Blue Silicone Collapsible Food Storage Containers with Airtight Lid, Air Vent, and Space-Saving Design - Microwave, Dishwasher, and Freezer Safe by Elizabeth Sheldon

I bought these almost a year ago and bought them for take away containers (instead of getting them in restaurants). I only managed to use them for this purpose a couple of times due to the restaurants being closed due to the pandemic last year. In this case, the largest container is no longer "locked". Almost as if a lid or container had been resized. I am so disappointed. I like the idea of saving space and waste. But I feel like I just wasted my money as one of them is completely useless at the moment. They are also not stain or odor resistant and will stain and absorb the odor of certain foods (e.g. foods with garlic, onions, red sauces, menus, etc.).
