These things are great. They hold more food than my previous meal prep containers and I got more of them for a lower price. If I had to point something negative out I would say that the seal is incredibly strong. I know it's good to have a strong seal to ensure freshness and whatnot but, seriously, I feel like I have to use a crowbar to get the things open sometimes. Doesn't bother me enough to give it any less than 5 stars, though.
