Are you bringing the party?
Make no mistake the food is (most of) the party. If your family and friends are willing to host so long as you bring food ( and personally, I would rather cook than vacuum) - this is a must-have item. And I imagine it would even work to bring a frozen casserole from the grocery if you're willing to provide but not cook.
Keeps hot things hot, cold things cold - makes carrying food very efficient and greatly minimizes the potential for any mess along the way. I did get a holiday-incentive discount, but it is worth full price. You will love it!
I recommend this product.
