Bought this 3 months ago. Within one day of use the left top lid holder crumbled away. Both top lids screws came lose - one after a month and the other just yesterday -  and we'll had to be dug out of food. Lids do not stay put. 

The top crocks should have been a little higher of the bottom one to keep lids on. 
Wish you could leave ladles in with a cut out in the lids. 
It keeps the heat and the space saving option is amazing. It's just the overall quality that unfortunately lacks. I was so excited to receive it and use it.
