Review on Set of 16 Plastic Food Containers with Lids - 1790, Locking Lids, Dishwasher Safe, Freezer Safe, Airtight - Ideal for Home, Kitchen, Storage & Organization by Darrick Dobbin

My initial reaction was positive as they are in three batches. Good space saver. I washed them in hot soapy water, rinsed, dried and left on the table overnight to dry completely. When I first started putting the lid on the smallest container, I found it difficult to close it. This was an issue with all containers. I've struggled to close a few, but most have taken a lot of effort and a few remain open. Not sure if it gets easier with use. I cannot recommend this product. UPDATE yes I can now. Two days later I am actually USING the jars and had no trouble opening or closing the lids. Filled and frozen several containers and again with no problems. I have no idea why they were so difficult to fold back up after washing and drying, but now they're easier to manage. Try it!
