The important thing to know is that this is the right size and product type to replace the heat pad for casserole packs that can keep food hot or cold

Perfect size

LIKE: Same size, shape, and manufacturer as the originals which we've used since 1995, until they recently started to lose ability to heat and hold temperature

Love the size of the microcore pac; especially the thickness.

They are the perfect size for carrying casseroles or putting in food delivery bags to keep things warm.

The smaller size would have worked better for me.

fits and works well - size was not listed in description, but took a chance

Love the size and they are so flexible.

wrong size for m carrier

nice size

Perfect size for the large casserole dishes

I returned this larger size hot-pack and exchanged it for the smaller sized one.

It is the proper size and model for our carrier

Good size

This is the right size and appears to be what I need.

Just the right size for our casserole dish.

Wrong size.
