Query: Works great.

I would have gave it a 5 star if the top lid was a little more rigid (like the bottom one is). I would have also preferred a better lid system that's easier to clean manually. Works ok if you put it in the dishwasher. This is just like the rubbermaid premier container lids which I cant stand. Everything else about the keeper works for me. Good construction, dishwasher safe, and works as intended. Recommended.
