To calculate the overall star rating and percentage breakdown by star, we do not use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
You get a bunch of size options. They hold and seal well at first, but if any moisture is one the bowl or top they do not work at all. This makes resealing after storing in the fridge almost impossible. I will be tossing these and buying something else.
If there's any moisture at all on the bowl, it'll slip right off and spill whatever is in the bowl. It also attracts lint and dust. However, it's a very cheap solution and it does work sometimes so it gets 2 stars.
I did not measure. A regular can (vegetables, olives, etc) measures just under 3 inches. These lids are too big for what I needed, standard can and jar covers. My fault. Trying again, for the third time.
