Bests & Worsts Reviews from Amazon

I purchased 3 of these containers for my kids to go to school. Love the colors. However, these containers don't open. I tried not putting food that's not too hot and not filling all the way to the top. I don't even tighten the lids all the way. I happened to all of them at least 3 times over the course of 2 months. The lid just keeps sucking itself down which closes on the fingers. The video was made 24 hours after the it happened so its not built up pressure. My other food containers dont do that. The last time it happened, I was able to open it the next day. I'm not going to continue using these because the kids end up not having lunch when it happens. Sad that I have to toss them.
