This is great. Researched a lot of options but came back to this one and glad I did. A lot of people complained about the latch. I agree it is tricky but once you learn the “trick” it's fine. Not sure if it will last over time, we've only had them a few weeks. My 8 year old can manage the latch no problem, 5 yr old has trouble. Love the stainless, no plastic, no leakage from one container to another, dishwasher safe, flat profile, food cup sizes and total volume. Those features are perfect for my kids.
